WebApr 24, 2024 · There are three types of triangles: equilateral, isosceles and scalene. The equilateral triangle has three sides that are all equal in length. The angles formed where sides of the triangle meet are all equal to 60 degrees. The isosceles triangle has two congruent sides, and two of its angles are also equal. WebTwo triangles with the same angles might be congruent: is congruent to: only because they are the same size But they might NOT be congruent because of different sizes: is NOT congruent to: all angles match, but one triangle is larger than the other! So just having the same angles is no guarantee they are congruent. Other Combinations oregon lighting company
