Translating and reflecting right triangles and rectangles on the coordinate plane - Mathematics Instructional Plan

This lesson is a remix from Illustrative Mathematics.  It focuses on right triangles.  It can include acute and obtuse triangles in the lesson.  Extensions of the lesson allow students to combine triangles to make other polygons.https://goopenva.org/courses/4-g-are-these-right

This resource asks students to determine where a third point could be to create a right triangle, an obtuse triangle, and an acute triangle.

This resource is a mini-flexbook on Pythagorean Theorem created by Shana Friend and provided through Ck12.org.

Students will complete a variety of Pythagorean Theorem word problems:ones where they must find a legones where they must find a hypotenuseones where they must find a perimeterones where they must find 2 legs.The activity is created so that the graph animates their solution to help them determine whethere the distance they found was too short, too long, or just right.

This activity is used for students to master solving problems using the following trigonometric functions: sine, cosine, and tangent. The activity is self checking, so students should be aware of their progress as they work.
