Which of the following methods would NOT be used to prove that two triangles are congruent? A. Prove that two sides and an included angle of one triangle are congruent to two sides and an included angle of the other triangle (SAS).
B. Prove all three sets of corresponding angles congruent (AAA).
C. Prove that two angles and an included side of one triangle are congruent to two angles and an included side of the other triangle (ASA).
D. Prove all three sets of corresponding sides congruent (SSS).

nswer: a   y-axis

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
