Name Date Module 1 Measurement Extension 1: Investigating Triangles Learning objective: Extend skills by applying concepts of measurement to real world or classroom problems. (CLO 1) Triangle 1 B A C Triangle 2 C Triangle 3 1. A You need to either print or copy the triangles above onto paper and cut them out. Keep track of which triangle is which for the later questions. Also, for a later question, make sure that you put the name of each angle on the inside of the triangle as well. Use a protractor to measure Angles A, B, and C for each Triangle. If you do not know how to use a protractor, or you don't have access to a protractor, here is a site that will help (you don't need to purchase a protractor). Math is Fun: Using a Protractor _ Triangle 1 Triangle 2 Triangle 3 What do you notice about your sums of all three angles? Take each triangle and rip off the angles A, B, and C, making sure you keep the letter on the part you rip off. Line up the angles from each triangle together along a horizontal line on your desk or paper. (You can use this activity if you printed it). The angle letters should line up next to each other, and the ripped edges of your angles should be the outside edges (not on your horizontal line). Take a picture of the angles from each triangle and put them here. 10. 1. Triangle 1 Triangle 2 Triangle 3 . What do you notice about the sums of the three interior angles of a triangle? .
