What is the actual length of the truck?
2) I can compute lengths and areas from scale drawings using multiple strategies.
On a scale drawing of a basketball court, 1 inch equals 8 feet. What is the actual area of the basketball court if the scale drawing is 11.75 inches by 6.25 inches?
3) I can determine if there is a unique triangle, more than one triangle, or no triangle using rulers, protractors and technology.
Can more than one triangle be drawn with side lengths of 5 inches and 7 inches and an included angle with a measure of 50°?
4) I can use properties of angles to solve for an unknown angle.
