Which are the coordinates of the vertices of a triangle congruent to ΔPQR?
2 answers:
Answer:
(4,3), (−4,8), (−4,3)
(2.5,−4), (0,0), (0,−4)
Step-by-step explanation:
On plotting on graph all form right angled triangle.
Dimension of all triangles and tanФ
Base=2 Height=5 tanФ 2.5 Base=5 Height=3 tanФ 1.6 Base=8 Height=5 tanФ 1.6 Base =2.5 Height=4 tanФ 1.6 [Here base and height can be interchanged if needed]
Ratio of perpendicular and base of last two triangle is equal.
First two are not congruent to any of other triangle but 3rd and 4th triangle are congruent .
Their coordinates are:
(4,3), (−4,8), (−4,3)
(2.5,−4), (0,0), (0,−4)

Step-by-step explanation:
Because if u look left to right on one triangle there is a angle and in between they have a com on line and on the right theres another angle so There for it’s angle side angle
Triangles with a 90 degree angle. We use the sine, cosine and tangent functions to determine the missing angles and sides.
