located at (2, 2), (5,-4), and (-
4,-1). What type of triangle is
triangle PQR? Select all that
apply.
Isosceles
Right angled
Scalene
Equilateral​

Answer 1

Answer:

Scalene triangle

Step-by-step explanation:

(2,2) = 4 units

(5,-4) = 1 units

(-4,-1) = -3 units

I write units because there has not written any units like cm, m, etc....

the PQR triangle has different side so we can said that this PQR triangle will be apply with Scalene triangle.

we know that:-

Isosceles : 2 side same...

Right angled : one side is to be 90⁰...

Scalene : different sides...

Equilateral : all same sides...

Answer 2

Answer:

first we will mark it's coordinates. the answer is isosceles triangle because length of PQ and QR is equal to 6 units but length of PR is 10 units.click on this photo
