Question

Help me please please please

Answer 1

i used to have the same math book and i think you did it right

Answer 2

So you have to draw two triangles
It will help if you will write the name of the point right by the point

Attached a graph
This is somewhat how it should look
This graph kinda made it look more squarish than the one you'll make but it should be similar.

Hope this helps :)
