if you add them they will equal 90degrees.

A minute of angle is one sixtyeth of an angle. If you had a circle and took one degrees out from it. Then you split that into 60 parts. 1 part would be a minute of angle.
If two sides and the included angle of one of one of the triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

It is complementary to one angle, supplementary to another.
Complimentary angles are two angles that add up to 90o. It the sum of two angles is 90o, and one is twice as big as the other, then we can make up a little equation to solve for that larger angle (a). It might look like this: 90o = a + ( a / 2 ) As our larger angle (a) was said to be twice as large as our smaller angle, our smaller angle (a/2) is half as large as the larger angle. 90o = 3a / 2 180o = 3a a = 180o / 3 = 60o Our mystery angle is a 60o angle. The smaller one is 30o. The larger angle is twice the smaller, and they two sum to 90o. Our work checks.
