the first exercise, though, we will review how to solve for a missing side using trigonometry. Exercise #1: Find the length of AB to the nearest tenth . Solving for a Missing Angle – The process for finding a missing angle in a right triangle is very similar Parts of a degree are now usually referred to decimally. For instance seven and a half degrees is now usually written 7.5°. When a single angle is drawn on a xy-plane for analysis, we’ll draw it in standard position with the vertex at the origin (0,0), one side of the angle along the x-axis, and the other side above the x-axis.

Draw the point of intersection between circle B and segment AB. Draw a circle with the center A and a radius equal to CB. Draw point E and create a ray from point B through point E. Find all the possible outcomes of flipping a coin (heads or tails) FOUR times. Side AB corresponds to Side DE, Side AC corresponds to Side DF, and Side BC corresponds to side EF. If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. Let's find the length of side DF, labeled x. We can write a proportion, like this:

Radians, Arc Length, and Area of a Sector . Two rays that have a common endpoint (vertex) form an angle. One ray is the initial side and the other is the terminal side. We typically will draw angles in the coordinate plane with the initial side along the positive 𝑥𝑥-axis. A . Terminal side . θ B Vertex. C Initial Side • The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. • The sum of the three angles of a triangle is 180°. • A triangle is said to be equilateral, if each of its sides has the same length. • In an equilateral triangle, each angle has measure 60°. The opposite sides of a parallelogram are congruent. Triangles can be used to prove this rule about the opposite sides. To explore these rules governing the sides of a parallelogram use Math Warehouse's interactive parallelogram. Find the area of each regular polygon.
