Rectangles

Curated and Reviewed by Lesson Planet

In this rectangles worksheet, 10th graders solve 6 different geometry problems that are related to the quadrilateral, rectangle. First, they find the values of x and y to determine if quadrilateral RSTV is a rectangle. Then, students determine whether ABCD, the last rectangle on the sheet, is a rectangle and explain their reasoning for their response.
