 Emma'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.

Weekly Blog 22 Hello again!

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
