26. KNG is an isosceles triangle with K as the vertex angle, and KN  5x  2 , and
GK  2x  4 .
a. Draw a diagram and label the angles and the sides with their lengths in algebraic
form.
b. What is the length of KN ?
…Of KG ?
c. For what range of values for GN will the lengths still form a triangle ?
d. Make a table of lengths possible for NG . (Use only integers)
e. Using the range of values above, find 1 value that will form an ACUTE triangle.
Justify using the Pythagorean theorem.
f. Using the range of values above, find 1 value that will form an OBTUSE triangle.
Justify using the Pythagorean theorem.

Why are the following triangles are congruent? Justify your reasoning! Be sure to use the
phrase “two sides and the included angle are congruent” instead of SAS!
32. Given : AB  CD ; AD  BC
33. Given: AE  BC ; E  C
Prove : ∆ABD  ∆ CDB
D is the midpoint of EC
Prove: ∆ADE  ∆BDC
34. Determine which postulate can be used to prove the triangles are congruent. If the
triangles cannot be proven congruent write NONE. Be sure to write out the postulate
(EX: 2 sides and the included angle are congruent instead of SAS)
