Chapter 4: Congruent Triangles
Triangle Measurements
A I know the Triangle Sum Theorem means the three angles in any triangle will always sum to 180 .
B I can use the Triangle Sum Theorem to calculate the measure of unknown angles in a triangle.
I know the Exterior Angle Theorem means the measure of the exterior angle is equal to the sum of
C
the two nonadjacent interior angles (inside angles that do not touch the exterior angle)
D I can use the Exterior Angle Theorem to calculate the measure of unknown angles in a triangle.
I can calculate the angle measures of an isosceles triangle using the Base Angle Theorem (base
E
angles of an isosceles triangle are always congruent).
I can calculate the side length of an isosceles triangle using the Converse of the Base Angles Theorem
F
(two legs of an isosceles triangle are always congruent).
G I can calculate the angle measure of an equilateral/equiangular triangle.
Geometry Vocabulary, Figures, Notation
H I can classify triangles by sides: equilateral, isosceles, and scalene.
I I can classify triangles by angles: acute, equiangular, right, and obtuse.
J I can name a triangle using the correct notation: for example, ABC
K I can identify the vertex, interior angles, and exterior angles in a triangle.
L I can identify and label the legs and hypotenuse of a right triangle
M I can identify and label the legs, base, and base angles of an isosceles triangle.
Proving Triangles Congruent
XYZ
N I can write a congruence statement for two congruent triangles: for example, ABC
I can identify the corresponding angles and sides of a triangle when given a congruence statement or
O
a picture of congruent triangles.
P
I can prove two triangles are congruent using SSS, SAS, AAS, ASA, or HL when given a picture.
Q
I can write a two column proof to prove two triangles are congruent (SSS, SAS, AAS, ASA, or HL).
R
I can write a two column proof to prove that corresponding parts of congruent triangles are
congruent (CPCTC).
