| Is there a Angle-Angle-Angle Postulate? | No.
🗑
|

| Define the Side-Angle-Side Postulate. | If two sides and the angle in between in one triangle are congruent to two sides and the angle in between in a different triangle, then the two triangles are congruent.
🗑
|
||||
| What is the Angle-Side-Angle Postulate? | If two angles and the included side in one triangle are congruent to two angles and the included side in a different triangle, then the two triangles are congruent.

| What is the 45-45-90 Triangle Theorem? | In any 45-45-90 triangle, the length of the hypotenuse is the product of the square root of 2 and the length of a leg.
🗑
|
||||
| What is the 30-60-90 Triangle Theorem? | For any 30-60-90 triangle, the length of the hypotenuse is 2x the length of the shorter leg and the length of the longer leg is the square root of 3 x the length of the shorter leg.
🗑
