Triangle Congruence
100
Two angles whose sum adds up to 180 degrees.
What are SUPPLEMENTARY ANGLES?
100
An angle whose measure is exactly 90 degrees.
What is a RIGHT ANGLE?
100
AB + BC = AC is an example of this postulate.
What is the SEGMENT ADDITION POSTULATE?
100
GIVEN: Line L is parallel to line M.
PROVE: Angle 1 is congruent to angle 2.
What is the ALTERNATE INTERIOR ANGLES THEOREM?
100
What is SSS?
200
Corresponding parts of congruent triangles are congruent is an example of this.
What is CPCTC?
200
A line or ray that divides the a line segment into two equal parts.
What is a SEGMENT BISECTOR?
200
If lines L and M are parallel, then m<4 + m<6 = 180.
What is the SAME-SIDE INTERIOR ANGLES POSTULATE?
200
GIVEN: Angle 1 is congruent to angle 2.
PROVE: Line L is parallel to line M.
What is the CONVERSE OF THE ALTERNATE INTERIOR ANGLES THEOREM?
200
What is SAS?
300
Two angles whose sum adds up to 90 degrees.
What are COMPLIMENTARY ANGLES?
300
A line or ray that divides an existing angle into two angles of equal measure.
What is an ANGLE BISECTOR?
300
<1 + <2 = <ABC is an example of this postulate.
What is the ANGLE ADDITION POSTULATE?
300
Prove angle 1 and 3 are congruent.
What is the VERTICAL ANGLES THEOREM?
300
ASA
400
A point on a segment that divides a it into two equal segments.
What is the DEFINITION OF A MIDPOINT?
400
Two adjacent supplementary angles that are formed by two intersecting lines.
What is the DEFINITION OF LINEAR PAIR ANGLES?
400
3a(10a + 10) = 30a2 + 30a
What is the DISTRIBUTIVE PROPERTY?
400
Why are obtuse angles always depressed?
Because they are never "right".
400
What is AAS?
500
Two lines that intersect or are coincident that form a right angle.
What is the DEFINITION OF PERPENDICULAR LINES?
500
The size and shape are the same, therefore they also have equal measurements.
What is the DEFINITION OF CONGRUENCE?
500
5 + (-5) = 0 = (-5) + 5 is an example of what property.
What is the ADDITIVE INVERSE PROPERTY?
500
Why was 6 afraid of 7?
Because 7 ate 9.
500
