Please help? The pair of polygons at the right is congruent. What is m∠J? (Picture on next post)
Here's the picture for the question...
I can pick from these: - 45 - 90 - 135 - 145
ok all your angles have to add to 360, you have 2 90degree angles and a 135 degree angle. 90+90+135=315 360-315=45
Oh I see... Since a triangle's angles add up to 36 degrees and there's two 90 degree angles made from the square... Thank you!!
