On this interactive website students practice various math skills using a real life scenario. Those skills include finding angles, drawing angles larger or smaller than a given angle, and locating right angles.

In this lesson students will practice finding the area rectangular shapes and irregular shapes with right angles and understand why the area formula works for rectangular shapes.

This lesson plan provides students with an opportunity to practice drawing and measuring triangles and angles. It also shows pictures and gives definitions of each type of angle and triangle.

Explains what "tangent" is and its role in the right triangle. Slope of a line is investigated and tangent for special common angles is given. Angle of elevation and angle of depression are also covered here.

In this instructional activity, students learn to classify triangles by the size of the angles and the measures of the sides. Students will use interactives to explore equilateral, isosceles, scalene, acute, obtuse, and right triangles....
