Two triangles are congruent because two pairs of corresponding sides and the included angle are congruent
What is SAS?
100
Has two congruent sides called legs.
What is Isosceles Triangle
200
Two equal sides and angles
Isosceles
200
The value of all three angles in a triangle added together.
180 degrees
200
If the hypotenuse (H) and 1 side (S) of a right-angled (R) triangle re equal to the hypotenuse and 1 side of another right-angled triangle, then the two right-angled triangles are congruent.
RHS
200
The sum of the two acute angles in a right triangle.
What is 90 degrees
200
All three sides are congruent.
What is Equilateral Triangle
300
All sides and angles are equal.
Equilateral
300
When two lines intersect the opposite angles are equal to each other.
vertical angles
300
If 2 sides and the included angle angle of a triangle are equal to the 2 corresponding sides and the corresponding included angle of another triangle, then the two triangles are congruent
SAS
300
Two angles of a triangle and the included side are congruent to the corresponding angles and sides of another triangle.
What is ASA
300
All three angles equal 60 degrees.
What is Equiangular.
400
Has an angle whose measurement is greater then 90 degrees.
Obtuse
400
The little box in the corner of a triangle.
90 degrees.
400
If two angles and the non-included side one triangle are congruent to two angles and the non-included angle of another triangle, then these two triangles are congruent.
AAS
400
A part of a triangle that is congruent to itself
The reflexive property
400
The non congruent side of an isosceles triangle.
What is a base
500
All angles measure less than 90 degrees.
acute.
500
ALL corresponding lengths are equal and all corresponding angles are equal
Congruent triangles
500
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
What is SSS
500
Besides one angle you need this number of sides to prove a right triangle congruent?
