Question

please help!!

Polygon P'Q'R'S'T' shown on the grid below is an image of polygon PQRST after dilation with a scale factor of 3, keeping the origin as the center of dilation: http://prnt.sc/d5zw7c

Which statement about corresponding sides and angles of the two polygons is correct?
The measures of angle Q and angle Q' are in the ratio 1:3.
The length of side TS is equal to the length of side T'S'.
The length of diagonal RT is equal to the length of diagonal R'T'.
The lengths of side SR and side S'R' are in the ratio 1:3.

Answer 1

dialation affects length not angles

Answer 2

for example if u look at a triangle closely or from a far away the angles in the triangles are still the same

Answer 3

ah okay

Answer 4

to find a dialation u can look at any vector on each polygon and see how that vector changed on the otehr polygon

Answer 5

consider this vector

Answer 7

The lengths of side SR and side S'R' are in the ratio 1:3.

Answer 8

if you are ever really confused, u can just use pythagorean thm to find the lengths you want

Answer 9

pythagorean?

Answer 11

yes pythagorean thm is an equation that lets you find the hypotenuese of right angle triangles

Answer 12

a^2+b^2=c^2

Answer 13

where c is the hypotenuese and a and b are known as the legs of the triangle

Answer 14

oh okayy i get it.. thanks

Answer 15

okay sure ^^
