Thus, angles 2 and 3 are complementary.
Step-by-step explanation:
Complementary angles are two or more angles that their sum equals
. Given that: i. <1 and <2 are complementary
ii. <1 ≅ <3
iii. <2 ≅ <4
Prove that: <2 and <3 are complementary
Proof:
<1 + <2 =
(complementary angles)
<1 ≅ <3 (congruent property)
<2 ≅ <4 (congruent property)
⇒ <3 + <4 =
(complementary angles by congruent property)
Since <1 ≅ <3,
∴ <2 + <3 =![90^{o}](/tpl/images/0811/0257/9fbdd.png)
Thus, angles 2 and 3 are complementary
