Questions & Step-by-Step Solutions
If two angles of a triangle are equal, what type of triangle is it?
Step 1: Understand that a triangle has three angles.
Step 2: Identify that if two angles in a triangle are equal, it means they have the same measure.
Step 3: Recall the definition of an isosceles triangle, which is a triangle with at least two equal sides and the angles opposite those sides are also equal.
Step 4: Conclude that since two angles are equal, the triangle must be isosceles.
Isosceles Triangle – A triangle with at least two equal angles, which also means it has at least two equal sides.
