Math Trivia #1: Properties of Triangles
Try this geometry trivia question on your child: You have a triangle. One angle is 65 degrees. The second is 75 degrees. What's the measure of the third angle? To figure it out, your kid must add 65 to 75 to get 140. Then, since all angles in a triangle add up to 180 degrees, he must subtract 140 from 180 to get the last angle: 40 degrees.
