Leg geometry definition9/5/2023 ![]() ![]() This puts ∠A to the bottom left, and ∠B to the bottom right.Ĭonstruct an altitude (or height) h from the interior right angle C to hypotenuse c (so it is perpendicular to c). The right triangle altitude theorem tells us that the altitude of a right triangle drawn to the hypotenuse c forms two similar right triangles that are also similar to the original right triangle.Ĭonstruct △ABC so that hypotenuse c is horizontal and opposite right angle C, meaning legs aa and bb are intersecting above c to form the right angle C. Learn how to use the Pythagorean Theorem to calculate the length of one side of a right triangle. The sum of the squares of legs, a and b , are equal to the square of hypotenuse, c, or The Pythagorean Theorem describes the relationship between the lengths of legs a and b of any right triangle to the length of hypotenuse, c: Greek mathematician Pythagoras gets the credit, but other civilizations knew about this theorem. If you connect the two endpoints of those line segments, you have a right triangle. Follow the lines to make a second line segment exactly 90° to your first line segment, of any desired length. Draw a line segment (of any desired length) along the graph paper's printed lines. ![]() You can make a more accurate right triangle by using graph paper and a straightedge. Laying the third strand c down to intersect the two endpoints of aa and bb creates a right triangle. Place the two short strands a and b so they meet at two endpoints and form a 90° angle. Leave one alone break the other strand into two unequal lengths. Use two uncooked spaghetti strands to make your own right triangle. ![]() It can be scalene or isosceles but never equilateral. A right triangle must have one interior angle of exactly 90°. ![]()
