Based on the distance between triangles ABC and A'B'C', the line of reflection that reflects ABC to A'B'C' is (x = 1).

<h3>Where is the line of reflection?</h3>

To find this out, you can use the coordinates of a point in triangle ABC and it's corresponding point in  A'B'C'.

The coordinates of B is (3, 2)

The coordinates of B' is (-1, 2)

Find the midpoint between these points:
= ( (x₁ + x₂) / 2), ((y₁ - y₂) /2)

= (( 3 + (-1)) / 2 ) , ((2 - 2) / 2))

= (1, 0)

This shows that the line of reflection is x = 1.

A rectangular piece of paper with length 35 cm and a width 18 cm has two semicircles cut out of it as shown below
Eddi Din [679]

Answer:

375.66 cm²

Step-by-step explanation:

The two semicircles add to a full circle.

For the circle, d = 18 cm.

r = d/2 = 9 cm.

A = LW - πr²

A = (35 cm)(18 cm) - 3.14(9 cm)²

A = 375.66 cm²

The shortest side of a triangle is 12cm and the area of the triangle is 8 square cm. A similar triangle has an area of 18 square
sdas [7]

Answer:

27cm

Step-by-step explanation:

Given the following :

Triangle A:

Shortest side = 12cm

Area of triangle = 8cm^2

Triangle B:

shortest side =?

AREA of triangle = 18cm^2

If triangle A and B are similar :.

Area A / Area B = Length A / length B

8cm^2 / 18 = 12 / length B

Cross multiply :

8cm * Length B = 18 × 12

Length B = 216 / 8

Length B = 27

Therefore, the shortest of the other triangle IS 27cm
