Answer:
You would explain what I did in the step by step explanation.
Step-by-step explanation:
There are three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all 3 sides congruent, an isosceles has only 2 sides congruent, and a scalene has no sides congruent. So, if the triangle has marked sides congruent, or you have found some sides congruent, then you look at the amount of sides congruent, and then you can find the type of triangle. For example, if you have a triangle called ABC, and AB and BC are congruent but AC is not, then it is Isosceles because 2 sides are congruent. You would explain the 3 triangle definitions to your friend.
