# Does a right angled triangle have all equal sides?

right angled triangle does not have all equal sides

### Does a right-angled triangle have any equal sides?

A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle. Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.

### In a right angled triangle ABC the hypotenuse AC is equal to what?

In a right angled triangle its hypotenuse when squared is equal to the sum of its squared sides which is Pythagoras' theorem for a right angle triangle.

### A triangle has 1 right angle and 2 equal sides what two words describe this triangle?

no. according to Pythagoras. If a, b,c are 3 sides of a right angled triangle, a2 +b2 = c2

### Is a right-angled-triangle a regular polygon?

No. A regular polygon has all sides equal and all angles equal. Neither of those properties can be true of a right triangle. A regular triangle is an 'equilateral one'. Its sides are equal, and each of its angles is 60 degrees.

### Does a right angle triangle have equal sides?

No, all three sides of a right angle triangle cannot be equal. In a right angled triangle, the side opposite the right angle - the hypotenuse - will always be the longest side of the triangle. The remaining two sides may be equal to each other, but they don't have to be.

### Can a right triangle have three acute angles and three equal sides?

No, a right angled triangle cannot have three acute angles because an acute angle is less than 90 degrees and a right angled triangle has one angle of exactly 90 degrees (which is what right angled means, equal to 90 degrees). Also, because the triangle has a right angle (of 90 degrees) it cannot have three equal sides; it can have two equal sides but the side opposite to the right angle (the hypotenuse) will… Read More

### Classify the triangle by its angles?

### How many sides does a right angled triangle?

ALL triangles have three sides and three angles. The three angles always add up to 180 degrees. A right angled triangle has one 90 degree right angle and two smaller angles.

The 4 types of triangles in Geometry are Isosceles, Equilateral, right angled and Scalene. A Scalene triangle will have no equal sides and no equal angles. An Isosceles triangle will have 2 sides that are of equal length and 2 angles of equal degrees. An Equilateral triangle will have all 3 sides being the same length and all angles will be of the same degrees (60 degrees). A right angled or right triangle has a… Read More

### Classify the triangle by its angles and by its sides?

All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).

### What is the definition for leg of a triangle?

There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.

### Can a triangle have perpendiculer sides?

yes and then it will be called a right-angled triangle

### Can you determine the type of a triangle by just knowing it's sides?

Yes. The three sides uniquely specify the triangle. If all three sides are equal it is equilateral. If only two are equal it is isosceles. If none are equal it is scalene. If the sum of the squares of the two shorter lengths is equal to the square of the longest length, it is a right angled triangle. If the sum of the squares on the two shorter sides is less than the square on… Read More

### What is The Difference Between an equilateral triangle And A Right Angled Triangle?

An equilateral triangle has all sides the same length and all its angles are 60dgrees. A right angled triangle is just a triangle with a right angle.

### Does the pythagorean theorem have a converse?

Yes. If the square of the longest side of a triangle is equal to the sum of the squares on the other two sides, then the triangle is right angled.

### Can a right-angled triangle be isosceles?

Yes, it is called a right isosceles triangle. The the longest side is across from the right angles as usual, and the other two sides are of equal distance

### What is Pythagoras famous famous for?

Pythagoras is famous for his theorem that "in a right-angled triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides." Basically, you have a right-angled triangle. The long side is the hypotenuse. Square it (times it by itself) and square the other two sides as well. The hypotenuse squared is equal to the other two sides squared.

### What is the pythagerean theorem?

It states that, in an right-angled triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

### How many parallel sides does a right angled trangle have?

A right angle triangle has no parallel sides

### Can a triangle with side lengths of 8 15 and 17 be a right triangle?

Add the squares of the two smaller sides. Is it equal to the square of the biggest side? If yes, it is a right angled triangle. 82 + 152 = 64 + 225 = 289 172 = 289 The same, so it is right angled.

### What are the shapes of triangles called?

One way of classifying triangles is by the number of equal sides. An equilateral triangle has all three sides of equal length. All three of its angles are also and since they add up to 180 degrees, each one is 60 degrees. It is sometimes called an equiangular triangle. An isosceles triangle has two equal sides. The angles that each of these sides forms with the third side are equal. A scalene triangle has no… Read More

### What is the difference between an isosceles triangle and a right triangle?

In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle… Read More

### Can a pythagorean triple have two equal sides?

In any Pythagorean triple, the square of the two shortest sides is equal to the square of the longest side. For example, 32+42=52. Since it is impossible to have a right-angled triangle with a side of 1, it is impossible for two sides of a right-angled triangle to be of the same length. Therefore, a Pythagorean triple will always contain three differently-sized sides.

### How do you find the hypotenuse of a non right triangle?

By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.

### What is the converse of Pythagoras's theorem?

The converse of Pythagoras's theorem states :- "If the square of one side of a triangle is equal to the sum of square of other two sides then the triangle is a right angled triangle""

### Is A triangle with sides of lengths 12 15 and 20 a right triangle?

No. Pythagoras' theorem states that when the square of the hypotenuse is equal to the sum of the squares of the other two sides then it is a right-angled triangle. The hypotenuse is the longest side (opposite the supposed right angle). In this case the hypotenuse is 20. The square of 20 is 400. The other two sides are 12 and 15. The square of 12 is 144 and the square of 15 is 225… Read More

-- Every triangle, no matter what its shape or size, has three angles inside it that add up to 180 degrees. -- Whyen you say "regular right angled triangle", I hope you don't mean that all three of its sides are the same length ... that's what "regular" usually means in geometry. It's impossible for a right triangle to have all of its sides equal.
