Q. If the coordinates of point A are (2, 3) and point B are (5, 7), what is the distance between points A and B?
A.
5 units
B.
4 units
C.
3 units
D.
6 units
Solution
Using the distance formula, d = √[(x2 - x1)² + (y2 - y1)²] = √[(5 - 2)² + (7 - 3)²] = √[3² + 4²] = √25 = 5 units.
Q. If triangle DEF is similar to triangle XYZ and the sides of DEF are 3 cm, 4 cm, and 5 cm, what are the lengths of the corresponding sides of triangle XYZ if the ratio of similarity is 2:1?
A.
6 cm, 8 cm, 10 cm
B.
3 cm, 4 cm, 5 cm
C.
1.5 cm, 2 cm, 2.5 cm
D.
4 cm, 5 cm, 6 cm
Solution
If the ratio of similarity is 2:1, then the sides of triangle XYZ will be 2 times the sides of triangle DEF, giving 6 cm, 8 cm, and 10 cm.
