Two equal angles of 40° each are increased by the same angle of 25°.
Which axiom guarantees the new angles (65° and 65°) are still equal, and what is their common value?

Question

Two equal angles of 40° each are increased by the same angle of 25°. Which axiom guarantees the new angles (65° and 65°) are still equal, and what is their common value?

Accepted Answer

65. By 'if equals are added to equals, the wholes are equal', 40 + 25 = 65° for each, and they remain equal.
