Similar figures

Answer 7

They have the same shape and corresponding sides. Corresponding angles have the same measure. The ratios of the corresponding sides in large or reduce by the same multiplier called the scale factor. (Ex; two triangles first sides 2-4 second sides 3-x if 2x2=4 the 3x2=x, which is 6. )

Question 8

Indirect measurement

Answer 8

The way you can measure something without measuring it directly like using shadows. (Ex: a statue is 6ft tall and its shadow is 3 ft. Long, a visitor next to it is 5ft. Tall how long is his shadow. 6 divided by 3 is 2, so 5 divided by = 2.5.
