Answer:

(Going clockwise from top left.) Rotation, Reflection across the x-axis, Reflection across the y-axis, translation.

Step-by-step explanation:

In picture one, the triangle seems to be rotated.

In picture two, the triangle is reflected across the x-axis.

Picture 3 has the triangle reflected as well, but this time it is across the y-axis.

Picture 4 has the triangle translated. It has no change in mirroring but it has a change in position.

A rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeter

Answer:

25%.

Step-by-step explanation:

Let E be the event that the dart lands inside the triangle.

We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.

We know that probability of an event represents the chance that an event will happen.

$\text{Probability}=\frac{\text{Favorable no. of events}}{\text{Total number of possible outcomes}}$

$\text{Probability that dart lands inside the triangle}=\frac{\text{Area of triangle}}{\text{Area of rectangle}}$

$\text{Probability that dart lands inside the triangle}=\frac{162}{648}$

$\text{Probability that dart lands inside the triangle}=0.25$

Convert into percentage:

$0.25\times 100\%=25\%$

Therefore, the probability that dart lands inside the triangle is 25%.
