Look at the pictures below to see what corresponding sides and angles look like.

Sides and angles math. These shapes must either be similar or congruent. Both are as easy as pie if you know the relationship between the side lengths and angles of a triangle. Corresponding sides and angles are a pair of matching angles or sides that are in the same spot in two different shapes. As you can see from the picture below if you add up all of the angles in a triangle the sum must equal 180.

To explore the truth of this rule try math warehouse s interactive triangle which allows you to drag around the different sides of a triangle and explore the relationship between the angles and sides. Same side interior angles theorem proof. The largest angle of the triangle is opposite to its longest side and the smallest angle is opposite to the shortest side.

Let l 1 and l 2 be parallel lines cut by a transversal t such that 2 and 3 in the figure below are interior angles on the same side of t. Let us show that 2 and 3 are supplementary. What are corresponding sides and angles. Since 1 and 2 form a linear pair then they are supplementary.
