Properties of a square |
A square is a parallelogram with 4 congruent sides, right angles, diagonals bisect, and the bisectors are perpendicular.
|
|
|
ASA congruence postulate |
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent.
|
|
|
Properties of a rectangle |
Parallelogram with 4 right angles. Opposite sides are congruent. Diagonals bisect each other. Opposite angles are congruent. Opposite sides are parallel. Not all sides are congruent.
|
|
|
AAS congruence postulate |
If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent.
|
|
|
SSS congruence postulate |
If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent.
|
|
|
HL congruence postulate |
If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the two triangles are congruent.
|
|
What property would you use to prove that these triangles are congruent?
|
SAS congruence postulate. |
|
What property proves that the quadrilateral is a parallelogram?
|
One pair of opposite sides are both congruent and parallel. |
|
What postulate proves that these triangles are congruent?
|
AAS congruence postulate. |
|
What property proves the quadrilateral is a parallelogram?
|
Opposite sides are congruent. |
|
What is the value of x? (This is a parallelogram)
|
Step 1: 2x+2=40 Step 2: 2x+2-2=40-2 Step 3: 2x=38 Step 4: 2x/2=38/2 Step 5: x=19 |
|
Is triangle CAB congruent to triangle FDE? If you said yes, what postulate did you use?
|
Yes, I used the HL congruence postulate. |
|
What property would prove these triangles congruent?
|
None, ASS or SSA is not a congruence postulate. (trick question) |
|
What postulate makes these triangles congruent?
|
SSS congruence postulate. |
|
What is the value of x? (This is a parallelogram)
|
X=80 degrees because opposite angles are congruent. |
