the correct answer is c in my book but how
Answers
(c) Two sides are equal.
is the correct answer by SSS congruence.
Explanation:
Two triangles are congruent if they meet one of the following criteria:
SSS: All three pairs of corresponding sides are equal.
Two triangles. Each side of the first triangle is congruent to one side of the second triangle.
SAS: Two pairs of corresponding sides and the corresponding angles between them are equal.
Two triangles. Two sides of the first triangle are congruent to two sides of the second triangle. The angle of the first triangle that is between the mentioned sides is congruent to the corresponding angle of the second triangle.
ASA: Two pairs of corresponding angles and the corresponding sides between them are equal.
Two triangles. Two angles of the first triangle are congruent to two angles of the second triangle. The side of the first triangle between the mentioned angles is congruent to the corresponding side of the second triangle.
AAS: Two pairs of corresponding angles and one pair of corresponding sides (not between the angles) are equal.
Two triangles. Two angles of the first triangle are congruent to two angles of the second triangle. The side of the first triangle that is not between the mentioned angles is congruent to the corresponding side of the second triangle.
HL: The pair of hypotenuses and another pair of corresponding sides are equal in two right triangles.
