If c∥d, name all angels that must be congruent to ∠1.

Short Answer

Expert verified

Angles congruent to∠1is∠6,∠9,and∠14.

Step by step solution

01

Step 1. Observations from figure

a is transversal to parallel linescandd

02

Step 2. Find corresponding angles

Corresponding angle to ∠1is ∠9

Postulate 10: If two parallel lines are cut by a transversal then the corresponding angles are congruent

Thus,∠1≅∠9

03

Step 3. Find vertically opposite angles

Vertically opposite angle to ∠1is∠6

Vertically opposite angle to ∠9is ∠14

Theorem 2-3: Vertically opposite angles are congruent, so ∠1≅∠6and∠9≅∠14.

04

Step 4. Use transitive property

If a=band b=cthen a=c

Substitute ∠1for a,∠6 for b, and ∠14for c

Since, ∠1≅∠6and ∠6≅∠14implies∠1≅∠14

Thus, angles congruent to ∠1is∠6,∠9,and∠14
