Using Properties of Angles to Solve Problems

If the sum of the measures of two angles is 90∘ 90 ∘, then the angles are complementary. If angle A A and angle B B are complementary, then m∠A+m∠B =90∘ m ∠ A + m ∠ B = 90 ∘. In this section and the next, you will be introduced to some common geometry formulas. We will adapt our Problem Solving Strategy for Geometry Applications.

Linear pair of angles: Sum of angles = 180°. Sum of angles at a point = 360°. 3. Find the measure of an angle which is complementary to 33°. Solution: If the sum of two angles is 90°, they are called complementary angles. Let x be the angle which is complementary to 33°. So, x + 33° = 90°. x = 90° - 33° = 57°.

7.1.5: Using Equations to Solve for Unknown Angles

To find an unknown angle measure, sometimes it is helpful to write and solve an equation that represents the situation. For example, suppose we want to know the value of x in this diagram. Figure 7.1.5.12. Using what we know about vertical angles, we can write the equation 3x + 90 = 144 to represent this situation. Then we can solve the equation.

Angle Properties

The sum of angles on a straight line is 180˚. Interior angles are supplementary. Supplementary angles are angles that add up to 180˚. The sum of angles in a triangle is 180˚. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of interior angles of a quadrilateral is 360˚.

Solving Triangles

This means we are given two angles of a triangle and one side, which is the side adjacent to the two given angles. In this case we find the third angle by using Angles of a Triangle, then use The Law of Sines to find each of the other two sides. See Solving "ASA" Triangles. 4. SAS. This means we are given two sides and the included angle.

To make our equation above more detailed: Smaller angle + Larger angle = 90°. Let x be the measure of the smaller angle. The measure of the larger angle is twice, or two times, the smaller, so we let 2x be the measure of the larger angle: x + 2x = 90. We can now solve the value of x above: x + 2x = 90.
