Answer:
14. B 9, Isosceles
15. Corresponding angles; alternate interior angles; verticle angles
Step-by-step explanation:
Question 14 explanation -
Because two of the triangle's angles are congruent, this triangle classifies as an Isosceles Triangle. Therefore, we know that sides AB and AC must be congruent. This makes it easy to solve for x...just set both side lengths equal to each other and solve.
mAB = mAC
16 = x + 7
16 - 7 = x + 7 - 7
9 = x
x = 9

It will help to graph it, so that you can see the shape. However, you can also just solve it by looking at the vertices. If you graph it, you'll see that the shape is a trapezoid. The two bases are 4 and 6, while the height is 5 - 1 = 4. So, we solve by using the equation for the area of a trapezoid: (6 + 4) * 4 * .5 = 20 units squared.
