Lesson 3: Practice Problems
Problem 1
Here is Quadrilateral
![Quadrilateral ABCD is on a grid. Point a is 2 units right and 4 units down from the edge of the grid. Point B is 2 units right and 2 units up from point A. Point C is 6 units right from point A. Point D is 2 units right and 4 units down from point A.](../../../../../../embeds/1bcf2cbb--7.1.PP.New.Image.05.png)

Problem 2
Rectangles
![Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R.](../../../../../../embeds/167915f3--7.1.A.PP.Image.22.png)

Problem 6 From Unit 1 Lesson 13
The line has been partitioned into three angles.
![A line partitioned into 3 angles. From left to right: 39, 99, and 42 degrees.](../../../../../../embeds/680977b3--8.1.D.PP.Image.04.5.png)
Is there a triangle with these three angle measures? Explain.
