Answer: (a) isosceles (b) right
<u>Step-by-step explanation:</u>
(a) All sides of a rhombus are congruent → PN = AN
Therefore, ΔPNA has two congruent sides so is ISCOSCELES
(b) The diagonals of a rhombus are perpendicular (equal to 90°)
Therefore, ∠PEL = 90° so ΔPEL is a RIGHT triangle
I only know the slope intercept form ones:
y+7=-2x-3
y=-2x-10
y-5=3x-2
y=3x+3
Hope this helps at least a little :3
