Chapter 10: Measurement, Area and Volume

Tell whether the figure is a polygon. If it is a polygon, classify it and tell whether it is a convex or concave. If not, explain why.

Solve the proportion.

$\frac{90}{15}=\frac{t}{34}$

Find the unknown base or height of the trapezoid.

$A=12{\text{ft}}^2,b_1=2\text{ft},b_2=\underset{¯}{?},h=3\text{ft}$

Tell whether the figure is a polygon. If it is a polygon, classify it and tell whether it is a convex or concave. If not, explain why.

Find the value of x. Then classify the triangle by its angle measures.
