In quadrilateral HJKL shown below, point J can be mapped to point K by a 46 counterclockwise rotation about point H, and point K
can be mapped to point L by a 72 counterclockwise rotation about point H.
Explain why HJ must be congruent to HL.
Determine the measure of HJL

Answer:
Point-Slope form:
standard form:
Step-by-step explanation:
The standard form is given by:
The point-slope form is given by:
- <em>Let's call
as point
, and</em>
<em>point as point
</em>
- <em>We also know that the slope
is given by
</em>
Let's find the slope:
1. So, point slope form can be written as:
2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:
<em>But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:</em>
<em>We can factor out a 3, so it becomes:</em>
So standard form is
