Time for Triangles. What is a triangle? A triangle is a polygon. It has 3 sides and 3 angles. It can also be called a trigon.

Classifying Triangles How many degrees can be found in all triangles? 180 We can classify triangles 2 ways: By their angles By their sides.

Triangles and Angles Classifying Triangles. Triangle Classification by Sides Equilateral 3 congruent sides Isosceles 2 congruent sides Scalene No congruent.

Sum of Angles in Triangles. Triangles classified by sides A scalene triangle has no congruent sides. An isosceles triangle has at least 2 congruent sides.

Classifying Triangles. Two Ways to Classify Triangles  By Their Sides  By Their Angles.

Scalene triangle: A scalene triangle is a triangle that has no equal sides. The following is a scalene triangle.

Name each polygon and tell whether it appears to be regular or not regular. nonagon, regular; octagon, not regular.

Sum of Angles in Triangles. Triangles classified by sides A scalene triangle has no congruent sides. An isosceles triangle has at least 2 congruent sides.
