Special Right Triangles Teacher Resources
Find Special Right Triangles educational ideas and activities
Students identify the characteristics of special right triangles. In this special right triangles lesson, students use rulers and protractors to draw triangles to specified conditions. They label triangles. Students use Java Sketchpad to complete triangle activities. Students discover the ratios for special right triangles. As an enrichment, they complete a math puzzle. Worksheets and activities are included.
In this special right triangles worksheet, 10th graders solve 9 different problems related to measuring various types of right triangles. First, they find the values of x and y in each right triangle shown. Then, students find the length of a diagonal of a square with the sides a given length. They also find the measures of an altitude of the triangle.
In this special right triangles worksheet, 10th graders solve and complete 16 different types of problems. First, they find the value of each variable. Then, students find the length of a side described to the nearest tenth of an inch. They also find the value of each variable and leave the answer in simplest radical form.
In this special right triangles worksheet, 10th graders solve 17 different problems that include measuring various angles of triangles. First, they determine the length of two line segments given the angles. Then, students determine the measure of an angle in a trapezoid as shown.
Eighth graders investigate direct and indirect measurement. In this eighth grade geometry and measurement lesson, 8th graders investigate a variety of methods for measuring the height of a tree. Students investigate and use the properties of similar triangles and special right triangles to solve application problems.
Students explore the concept of right triangles. In this right triangle lesson, students construct a scale model of a tourist attraction similar to Fort Jefferson. Students research aerial photos of Fort Jefferson, then build their model using posterboard, markers, tape, scissors, rulers, and other items.
Students use geometric formulas to divide a pumpkin pie. For this geometric formulas lesson, students review equations for area and circumference of a circle and divide a pumpkin pie to practice the formulas. Students use the Pythagorean theorem to solve the pie problems.
