 Taylor's Blog This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

Special Triangles

Last week we learned about special kinds of right triangles. There a 45, 45, 90's as well as 30, 60, 90's. The numbers are the measures of the angles in the triangle. For 45, 45, 90, both legs are the same length, and the hypotenuse is the elngth of the leg times the root of 2. An easy way to remember that, is that there are 2, sides the same, so the hypotenuse is times the square root of 2. For 30, 60, 90's the hypotenuse is double to short leg. The long leg is the short leg times the root of 3. An easy way to remember this one is that it has a 3 in 30, and each one of the 3 angles is a different measure, so the long leg is the short leg times the square root of 3.
