AB is a segment representing one side of isosceles right triangle ABC, with A (5,6) and B (2,2). Angle ABC is a right angle AB is congruent to BC. Find the two possible coordinates of vertex C.

ZoeyBiocth16:

is this geometry

silvernight269:

Yes

ZoeyBiocth16:

yea im in geometry and im not good

ZoeyBiocth16:

yea um not good at geometry

silvernight269:

Help?

Shadow:

An isosceles triangle is a triangle with two equal lengths. This is also a right triangle, which means it forms a 90 degree angle. Therefore you can draw another side that is equal in length to AB. This side must create a 90 degree angle as the hypotenuse is the side opposite to the 90 degree angle.

Shadow:

The second equal length you draw much be creating the 90 degree angle with AB, to be clear.

silvernight269:

I still don’t get it.

Shadow:

At what are you confused

silvernight269:

At the part on how I should draw it...

Shadow:

Start by drawing a side equal in length to AB that creates a 90 degree angle with AB.

Shadow:

It should be clear after that

silvernight269:

Have u seen the image that I took?

Shadow:

Yes, from B, Point A is 4 units up and 3 units right. Draw a line that goes 4 units up and three to the left. Same length. 90 degree angle. Do the same in the other direction.

Shadow:

From B, cant do that with A. That’s why it is the only two possible points.

silvernight269:

I see.

silvernight269:

So can I do for the other point of C, 4 units down and 3 units to the right?

silvernight269:

Shadow?

ZoeyBiocth16:

shadow is hard at work on this problem

Shadow:

yes

Shadow:

and no, was playing League, lol

ZoeyBiocth16:

silvernight269:

Yes. Thank you.

Shadow:
