 Weekly Blog 22 Lately we have been learning about right triangles. Sometimes, when given one or two side lengths it can be hard to find the third, but I have a method that can help. In a triangle with two 45 degree angles and one 90 degree angle: -To find the hypotenuse: H= root 2 * side You can remember this works for this type of triangle because there are two 45 degree angles, so root 2! In a triangle with a 30 degree angle, 60 degree angle, and 90 degree angle: -To find the hypotenuse: H= 2 * short side -To find the long side: L= root 3 * short side You can remember this by knowing that there is a 30 degree angle, so there has to be a short side! Hope that helps! Have a good week, Emma Article posted May 14, 2012 at 12:34 PM • comment • Reads 29 • Return to Blog List Add a CommentPosted Comments |
