Students learn how to use the Pythagorean theorem and are introduced to an important application of it.
Practice and explanation of using distance formula to calculate area and perimeter of shapes in the coordinate plane.
In this Khan Academy activity, students find the area and perimeter of a shape on a coordinate plane.
Images of rectangle on coordinate plane, one with easily identifiable area, other image with same rectangle rotated. Distance formula shown to calculate same area.
Definition of area of triangle, image of triangle on coordinate grid with height constructed. Area of triangle calculated using distance formula.
This activity promotes critical thinking and experimenting with triangles.
This task explores the real world topic of building light rails. Throughout the implementation of this task the students will learn about the cost of building railways and how to implement them within a budget. This task explores such mathematical concepts of using coordinates to find the distance between points, using coordinates to build polygons and find the area and length of sides, and writing equations of parallel lines.
CK-12 Foundation's Geometry FlexBook is a clear presentation of the essentials of geometry for the high school student. Topics include: Proof, Congruent Triangles, Quadrilaterals, Similarity, Perimeter & Area, Volume, and Transformations.
This video classifies shapes as quadrilaterals based on slope.
Lesson and practice problems using midpoint, slope and distance formula to prove that figures are certain types of quadrilaterals.
In this Khan Academy activity, students will solve word problems on a coordinate plane using the formulas for distance, area, and perimeter.
Class activity using distance formula, midpoint formula and cost to plan out a fictional trip
Texas Instruments activity exploring distances in the coordinate plane in order to classify shapes.
Students will use distance and perimeter on the coordinate plane to determine which fence company offers the best price for fencing a yard. Depending on the level of the class, students can use the Pythagorean Theorem or the distance formula.

CK-12's Basic Geometry FlexBook is designed to present students with geometric principles in a simpler, more graphics-oriented course. Students will explore geometry at a slower pace with an emphasis placed on visual aids and approachability.
Given a physical situation (e.g., a room of a certain shape and dimensions, with objects at certain positions and a robot moving across the room), students impose a coordinate system and describe the given in terms of polygonal regions, line segments, and points in the coordinate system.
