4. Circle the reflex angles. ما 5. Extend the arms of the angle marked with an arc. Then measure the angle. BONUS ▶Measure the other two angles in the triangle. Add the three angles. What is the sum of the angles in a triangle? 2. Use a protractor to check the triangle for right angles. Use a ruler to check it for equal sides. Then identify the triangle. BONUS ▶What is the measure of the angle marked with the arc? How can you tell without using a protractor? 3. Draw two non-congruent triangles. Use angle and size measures to explain why they are not congruent
