Standard(s): [MA2015] GEO (912) 17: Prove theorems about triangles. Theorems include a line parallel to one side of a triangle divides the other two proportionally, and conversely; and the Pythagorean Theorem proved using triangle similarity. [GSRT4]

Title: Interactive Geometry Dictionary: Lines in Geometry
Description:
This student interactive, from Illuminations, explores lines and their importance to geometry. Students can investigate the definitions and properties of perpendicular lines, segments, medians, Euler lines, and more.
Standard(s): [MA2015] GEO (912) 12: Make formal geometric constructions with a variety of tools and methods such as compass and straightedge, string, reflective devices, paper folding, and dynamic geometric software. Constructions include copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.

Title: IGD: Area of a Rectangle
Description:
This student interactive, from Illuminations, allows students to see interactively how to find the area of a rectangle by manipulating the length of two opposite sides of a rectangle. They discover that as the measurement of the base changes, the area of the rectangle remains base times height.
Standard(s): [MA2015] (6) 21: Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving realworld and mathematical problems. [6G1]
