use matrices to determine the coordinates of the vertices of the translated figure. Triangle DEF with vertex matrix [7 -9 -1 -7 -3 -7] translated 1 unites left and 4 units down.

(6, -11), (-10, -7) and (-2, -11)

Step-by-step explanation:

Coordinates of a triangle are represented in the form of a matrix as,

If the given triangle is shifted by 1 unit left and 4 units down,

Translation of vertices in the matrix form will be,

For a triangle having vertices (7, -7), (-9, -3) and (-1, -7) when shifted 1 units left and 4 units down will be,

=

=

Coordinates of the triangle after the translation will be,

(6, -11), (-10, -7) and (-2, -11)

∡ eia and ∡ kij are congruent

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show
