Question

Marie drew the triangle shown. She wants to draw a second triangle that is different from this one. Complete the statements about the second triangle. The second triangle is an equilateral triangle with side lengths ______ inches and angle measures ______ degrees.

1) 1.4, 60
2) 1.4, 90
3) 1.4, 120
4) 1.4, 180

Answer 1

The second triangle is an equilateral triangle with a side length of 1.4 inches and angle measures of 60 degrees.

Step-by-step explanation:

The second triangle is an equilateral triangle, which means all the sides are equal in length. Since Marie's first triangle has a side length of 1.4 inches, the second triangle will also have a side length of 1.4 inches.

In an equilateral triangle, all the angles are equal. Therefore, the angle measures of the second triangle will also be equal. Since the sum of all angles in a triangle is 180 degrees, each angle in the second triangle will measure 60 degrees.
