Introduction
Students will understand what is a right triangle and label its parts. They will recognize right triangles within other images and identify their parts. They will perform a webquest searching for similar figures. Students will also learn to solve for the length of one of the sides given the other two. Javascript will be used to make this part of the lesson more interactive. Subject:Algebra I and GeometryStandards Addressed California Standards for Mathematics This file is 544k and requires acrobat reader. Algebra 1 2.0) Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raisiing to a fractional power. They understand the rules of exponents. Geometry
1) Students know what is a right triangle, its legs and its hypotenuse. 2) Students can solve for the hypotenuse given the length of the legs. 3) Students can solve for the length of one of the legs given the lenght of the other leg and the hyponuse. Student ActivitiesIntroductory Activity Students are provided 3 images which have of right triangles inside of them.The right triangles are highlighted. The legs and hypotenuse are labeled. 1) in a street map 2) in a pyramid 3) in a baseball diamond The students are assigned to search the internet for more images that have right triangles in them. They can print out the images and highlight the right triangles. They should also label the 2 legs and the hypotenuse. Enabling

2) The students are given the distance from home plate to second base and the distance from first base to second. Show students how to calculate the distance from home plate to first base. Students will learn to solve for one of the legs given the hypotenuse and the other leg.Use javascript to generate another pythagorean triple and take the students through the steps of solving for a leg, correcting them as they go.
