- Learn to understand the angle measures of quadrilaterals. If you add the measure of the four interior angles of each quadrilateral shown above, the sum will equal 360°. Each of these quadrilaterals can be divided into two triangles.
- · A straight angle measures exactly 180°. · Before measuring an angle, students should first compare it to a right angle to determine whether the measure of the angle is less than or greater than 90°. · Students should understand how to work with a protractor or angle ruler as well as available computer software to measure and draw angles ...

- Interior Angles - Solve for x | Moderate. The measure of one of the interior angles is represented as a linear expression. Discern if the other indicated angle is congruent or supplementary to this angle, and evaluate the expression.
- Find the measure of each angle. Tell which postulate(s) or theorem(s) you used. 1. m∠10 = 2. m∠8 = 3. m∠9 = 4. m∠5 = 5. m∠11 = 6. m∠13 = For numbers 7 and ...

- If the measure of ∠6 = 120°, then the measure of ∠8 = . 22. If the measure of ∠7 = 50.5°, then the measure of ∠6 = . 23. If the measure of ∠3 = 118.7°, then the measure of ∠2 = . 24. RAINBOW A rainbow is formed when sunlight reﬂ ects off raindrops at different angles. For blue light, the measure of ∠2 is 40°. What is the
