Janet is designing a frame for a client. She wants to prove to her client that m∠AGE ≅ m∠CHE in her sketch. What is the missing
Amiraneli [1.4K]

Answer:

I believe the answer is transative property. I'm currently taking the test so I'm not 100% sure if I'm right yet.

Step-by-step explanation:

In step one, AGE and HGB are verticle angles since they are opposite of each other. then step two is alternate interior angles because they are interior angles opposite of each other, self-explanatory. the reason I choose the transitive property over the corresponding angles theorem is because the transitive property states: among A B and C, if A=B and B=c then A=C and in this case since AGE=HGB andHGB=CHE then AGE=CHE. I hope this helps and if you know the right answer just put it in the comments, if I'm wrong ofc.

Why do we say that light travels in straight lines? Is it strictly accurate to say that a laser beam provides a per- fectly stra
Aliun [14]

Answer:

Step-by-step explanation:

Light is considered to be without mass, but it has energy. According to Einstein, energy can be

equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is

so small that it can be ignored and so we say that light travels in a straight line.

The above statement does not hold true when light passes near a star. A star possesses a very

high gravity field that bends light such that the change of direction is observed.
