### What is three types of triangles?

They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles

### Are scalene and isosceles triangles similar?

No because they are different types of triangles

### When you are finding the area of a triangle do you do the same for all types of triangles?

yes. When you are finding the area of a triangle you do the same for all types of triangles.

### Why might two triangles not necessarily be congruent?

they might be different types of triangles.

### What will be the ratio of circles to triangles in a drawing showing 4 circles and 7 triangles?

4/(7) = 4/7 is the ratio of circles to triangles. Some prefer to express this as 4:7.

### What types of right triangles have all integer values for their sides?

isosceles right triangles

### What are the 3 types of triangle's?

3 type of triangles are isoceles acute and obtuse triangles.

### Can Pythagorean Theorem be used on all types of triangles?

No it can only be used with right angle triangles.

### What is an example of a sentence with a triangle in it?

There are three different types of triangles; equilateral, isosceles, and obtuse triangles.

### What kind of triangles make up a pyramid?

Many different types, but mostly equilateral triangles.

### How many triangles are in a pentagon with a star shape in the middle of the pentagon?

there are 35 triangles in a pentagon with a pentagram inside. We can see that there are seven different distinct types of triangles(you can cout them). Since you can rotate the triangle in five different ways we do 7*5 do i knw u telephone by lady gaga tik tok by k

### What are all of the types of triangles?

There are three basic types of triangles. Equilateral triangles have three congruent (equal) sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the two angles opposite those sides are also congruent. Scalene triangles have no congruent sides or angles. Right triangles are another type of triangle and they have one ninety-degree angle. Right triangles can either be scalene or isosceles.

### What are the properties of the different types of triangle?

There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.

### How many types of triangles are there and how many shapes are there all together?

There are countless number of shapes and triangles. Some different types of triangles are iscoleses, right and scalene. Some shapes are circle, triangle, square, hectagon, octagon, prism.....the list goes on and on and on......

### Are triangles equilateral?

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

### How many triangles are there in a heptagon?

seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles. There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles.

### What is triangle and who many types of triangle?

A triangle is a 2-dimensional closed shape (called a polygon) with 3 sides. The three sides form a closed shape with three interior angles, hence the name "tri-angle." There are three general types of triangles: they are called Acute, Obtuse, and Right Triangles. Acute Triangles contain interior angles that are all less than 90 degrees. Obtuse Triangles contain one (and only one) interior angle that is greater than 90 degrees. Right Triangles contain one (and… Read More

### What are the uses of triangles?

Triangles form other polygons as for instance there are 4 triangles in a 6 sided hexagon and 5 triangles in a 7 sided heptagon

### How are isosceles triangles and scalene triangles in common?

-- both types of triangle are plane (2-dimensional) figures -- both types of triangle have three sides -- both types of triangle have three interior angles that add up to 180 degrees -- in both types of triangle, sin(A)/a = sin(B)/b = sin(C)/c Those are the only characteristics shared by isosceles and scalene triangles.

### What are some types of triangles by degrees?

special triangles: 45-45-90 triangle and 30-60-90 triangle

### What shape has three different sized sides?

A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.

### Triangle puzzle - how many triangles?

### What is anther types of a triangles?

Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.

### A type of triangle with no equal sides?

There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.

### Some equilateral triangles are not isoscles?

They are both different types of triangles one has 3 equal sides and the other has 2 equal sides.

### Does all types of triangles have the same number of sides?

no they dont. the main type of triangles are isoceles equilateral and scarlene and they do not have the same numbers of sides
