Triangle ABC has the vertices A (2,2) B (6,2) C (6,8). It is reflected over the y-axis to make triangle A’B’C’. Mark claims that the new vertices of the triangle will be A’ (2,-2), B’ (6,-2), C’ (6,-8). Explain the errors that Mark made while determining the new vertices. Be sure to graph the correct transformation and include the correct vertices in your plot and explanation.

step-by-step explanation:

i hope this you : d

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

linear pair postulates

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
