Question

An isosceles triangle is to have a base that is 20cm long. Draw a diagram to show the following.

1. The legs can be very long.
2. Although the legs must be more than 10cm long, each length can be very close to 10cm.

Short answer

a. The diagram of isosceles triangle with very long legs.

b. The diagram of isosceles triangle with lengths of leg more than 10cm long.

Step-by-step solution

Part a. Step 1. Apply the concept of isosceles triangle.

An isosceles triangle is a triangle that has two sides of equal length.

Part a. Step 2. Step description.

Consider thatan isosceles triangle has a base that is 20 cm long.

Let’s draw a triangle first.

Here legs are far longer than base.

Part a. Step 3. Step description.

Thus, the triangle with very long legs is as follows:

Part b. Step 1. Apply the concept of isosceles triangle.

An isosceles triangle is a triangle that has two sides of equal length.

Part b. Step 2. Step description.

Consider thatan isosceles triangle has a base that is 20 cm long.

Let’s draw a triangle first.

Here, half of base is nearly equal to other sides.

Part b. Step 3. Step description.

Thus, the isosceles triangle which has legs very close to 10 cm is as follows:
