All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:-
Right angle triangle:a 90 degree angle and 2 acute angles
Scalene triangle: 3 acute angles
Obtuse triangle: an obtuse angle and 2 acute angles
Isosceles triangle: 2 equal base angles and an apex angle
Equilateral triangle: 3 equal angles each measuring 60 degrees

A triangle with all equal angles is called?
A triangle with three equal angles is an equilateral triangle.
Angles in a triangle?

What do you write when classifying triangles?
there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!
What is a triangle which all the angles are less than 90?
It is an acute triangle and if the acute angles are of different sizes then it is a scalene triangle.
What is the name for a triangle with all its angles different sizes.?
Scalene triangle.
What is a triangle with all angles in different size?
A scalene triangle has all sides and angles in different sizes.
What is one way an scalene triangle and equilateral triangle are different?
Scalene triangle: 3 interior angles of different sizes Equilateral triangle: 3 interior angles same sizes each of 60 degrees
A triangle with angles that measure 103 52 and 25?
An obtuse or a scalene triangle would have angles of the given sizes
What shape has all three sides and angles of different sizes?
A scalene triangle is a triangle in which there are no sides or angles with the same measures.
Examples of how to classift a triangle in two ways?
You can classify a triangle by its sides or by its angles. I.e: A triangle with three equal sides is an equilateral triangle A triangle with three equal angles is an equiangular triangle A triangle with two equal sides is an isosceles triangle
A triangle with angles that measure 32 79 and 69?
A scalene triangle would have angles of the given sizes.
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 acute angles.)
What shape has three sides and angles of different sizes?
Scalene Triangle
What triangle that has two equal sizes and the angles opposite the equal sides are also called?
isoceles triangle
