Prior Knowledge: I can use the Pythagorean Theorem
to find a missing side of a right triangle. (8.1)
PROOF OF UNDERSTANDING:
Prior Knowledge: I can label a right triangle with
“opposite”, “adjacent”, and “hypotenuse”. (8.3, 8.4)
PROOF OF UNDERSTANDING:
What is the length of side c? _____________
Look at the 2 example triangles above. First locate the
angles 60° and 35°. Then, label your triangles with H, O,
and A.

HSG.SRT.C.7: I can explain and use the relationship
between the sine and cosine in terms of
complementary angles.
PROOF OF UNDERSTANDING:
“I can” statements Right Triangles and Trig
HSG.SRT.C.7: I can use a trig ratio for sine, cosine or tangent to find the distance of a missing right triangle
side. (8.3, 8.4)
PROOF OF UNDERSTANDING:

PROOF OF UNDERSTANDING:
A research scientist at the South Pole has a tent with a center pole that is 7 feet high. If the sides of the tent
are supposed to make a 60 angle with the ground, how high is the tent? Draw and mark a diagram then
solve.
