4. Multiple Representation Write a different equation to find the angle measures in Example 2. Will the answer be the same? Explain.

As we know that the sum of angles of a triangle is 180⁰.

In Mathematics, an equilateral triangle:

From the given equilateral triangle, the equation can be written as:

x + x + x =  180⁰

As each angle is 60°.

so

60° + 60° + 60° = 180⁰

Therefore, each angle measure = x = 60°.

Yes! the answer is same, as the sum of angles of a triangle is 180⁰. The reason is that an equilateral triangle is said to be a triangle in which all three sides are equal. All three internal angles are also congruent to each other, each having 60° measure.

5. Draw Conclusion Triangle ABC is a right triangle. What conclusion can you draw about the measure of the angles of the triangle.

The Pythagorean Theorem defines the relationship in every right triangle such as:

A right isosceles triangle - having two same sides - has a 90° angle and two  90° angles.

Another kind of right triangle is the 30-60-90 degree triangle. Where one angle is right, 90°, and other two angles are 30° and 60°.

Another kind of right triangle is the 45-45-90 degree triangle. Where one angle is right, 90°, and other two angles are 45° and 45°.

So, we conclude that we have a variety of right triangles where one angle is the right angle, measuring 90° angle.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
