Question

Two triangles are similar
The lenght of the base of the bigger triangle is 30mm and that of the smaller triangle is 18mm
The height of the bigger triangle is 20mm
USING SCALE FACTOR
1.calculate the height of the smaller triangle
2.calculate the area of the bigger triangle
3.use the area scale factor to find the area of the smaller triangle

Answer 1

Answer:

1) the hight of the smaller triangle is 20mm

2) the 90mm²

3) the area of the smaller triangle is 50mm²

Answer 2

Answer:

When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles. In
