This an isosceles right triangle. The sides opposed to the angle 45° are congruent. Let x be this side==> x²+x² =(7√2)² (Pythagoras)

2x² = 49(2) ==> 2x²= 98  ==> x²=49 & x=7

(WILL GIVE BRAINLIST TO BEST ANSWER) What’s the missing angle based on the given angle measures.
matrenka [14]

Answer:

∠3 = 107°

Step-by-step explanation:

Similar to the other question, ∠3 and ∠4 are supplementary and add up to 180 degrees as they make up the entirety of a straight line.

∠4 is 73°, so ∠3 has to be 107°.

1. Rotate ABC 180° about the origin making<br> DEF.<br><br> List all congruent sides and angles:
Vedmedyk [2.9K]

Answer:

<h3>              ∠ABC≅∠DEF </h3><h3>              ∠BCA≅∠EFD </h3><h3>              ∠CAB≅∠FDE </h3><h3>           AB≅DE,  BC≅EF,  CA≅FD</h3>

Step-by-step explanation:

To rotate point A 180° about the origin (point O) we draw a line from that point (A) throu the origin, measure the distance from the point A to the origin, and then measure the same distance on the other side of the origin to get rotated point. Mark it. The angle at the rotated point will be congruent to ∠A

The same goes for points B and C

Angles at pair of given and rotated point are congruent.

Sides of triangle are congruent if they lay between two congruent angles.
