# How many equal angles and right angles has a obtuse triangle have?

An obtuse triangle can have no right angles, and has two equal angles.

### What type of triangle is angle abc obtuse acute or right?

If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle

### Has an isosceles triangle have an obtuse angle?

Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an…

### Which triangle is not an isosceles triangle?

An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle…

### What are the characteristics of the different types of triangles?

All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles

### What are the names of the three different triangles?

Classifications by side length or comparison of angles and sides: scalene - no sides or angles equal isosceles - two sides and angles equal (congruent) equilateral - all sides and angles equal (all 60° angles) Classifications by included angles : right triangle - contains a 90° angle (right angle) oblique triangle - has no right angle acute triangle - contains all angles less than 90° obtuse triangle - contains one angle greater than 90°

### What are the names of the 6 different triangles?

Classifications by side length or comparison of angles and sides: scalene - no sides or angles equal isosceles - two sides and angles equal (congruent) equilateral - all sides and angles equal (all 60° angles) Classifications by included angles : right triangle - contains a 90° angle (right angle) oblique triangle - has no right angle acute triangle - contains all angles less than 90° obtuse triangle - contains one angle greater than 90°

### How do you spell the names of different triangles?

Classifications by side length or comparison of angles and sides: scalene - no sides or angles equal isosceles - two sides and angles equal (congruent) equilateral - all sides and angles equal (all 60° angles) Classifications by included angles : right triangle - contains a 90° angle (right angle) oblique triangle - has no right angle acute triangle - contains all angles less than 90° obtuse triangle - contains one angle greater than 90°

### How do you classify a triangle by its angles?

If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be…

### Which polygon doesn't belong out of a rectangle and triangle and hexagon and trapezoid?

If the triangle and hexagon are equilateral, then the trapezoid is not like the others because all of its angles are not equal. A rectangle will have 4 equal right angles. An equilateral triangle will have 3 equal acute 60 degree angles. An equilateral hexagon will have 6 equal obtuse 120 degreeangles.

### What are the kinds of triangle acording to their angles?

### Different types of triangles can be created by combining 2 what terms scalene isosceles equilateral acute obtuse and right. What combination of these terms will not form triangles?

An equilateral triangle has to be acute. All the sides are the same size, and all the angles are the same size. You can't have three 90 degree angles in a triangle or three angles that are more than 90 degrees in a triangle. Therefore the angles have to be acute. An isosceles triangle will have two angles at are the same size. You can't have two 90 degree angles or two angles over 90…
