MEAP Preparation - Grade 7 Mathematics 4.13 Relation Between Sides and Angles of a Triangle

Points to remember:

The sum of the measures of any two sides of a triangle is greater than the measure of the third side.

The difference of the measures of any two sides of a triangle is less than the measure of the third side.

If two sides of a triangle are unequal, the measure of the angle opposite to the longer side is greater than the measure of the angle opposite to the shorter side.

If two angles of a triangles are unequal, then the side opposite to the greater angles is longer than the side opposite to the smaller angle.

No two angles of a scalene triangle are congruent.
