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,
