Translation

Use the above given to proof to answer the following question: What should replace (b) in the proof?
USQ and AQS are right angles
SUA and QAU are right angles

Use the above given to proof to answer the following question: What should replace (c) in the proof?
definition of right angles

definition of perpendicular lines

Use the above given to proof to answer the following question: What should replace (d) in the proof?
HL
LL
SSS
SSA

Use the above given to proof to answer the following question: What should replace (e) in the proof?
Definition of right angles
CPCTC
Definition of right triangles
Definition of square

Answer 1

(a) reflexive (which states that something is congruent to itself)

(b) USQ and AQS are right angles

(c) definition of perpendicular lines (two perpendicular lines form right angles)

(d) SSA (SSA theorem states that if two sides and one angle or two triangles are congruent, the two triangles are congruent)

(e) CPCTC ("Corresponding Parts of Congruent Triangles are Congruent")

Answer 2

a. transitive
b. USQ and AQS are rioght angles
c. defn of perpendicular lines
d. ssa
e cpctc
