Interior Angles of Triangles We are learning to…find the measure (in degrees) of missing interior angles in triangles. Saturday, May 24, 2014
Directions For Interior Angles of Triangles Activity: • Cut out each of the 3 triangles provided on the resource page. • Put a star in each of the interior angles on all 3 triangles. • For each triangle cut off the interior angles one at a time. • Place the interior angles together (so that the stars are touching) and tape the angles to these notes. • Predict the sum of the angle measure of each triangle based on what you observe.
Interior angles of triangles… The sum of the interior angles of any triangle is: 180 °
Find the missing measure of the interior on the triangle below: 20° + 130° = 150° 180 – 150° = 30° 20° ?° 130° Try finding the missing interior angles of several triangles with your team!
