For this case we have that by definition:
A triangle is defined by three lines that are called sides, or by three points called vertices.
We know that:
- <em>The vertices of a triangle are labeled with capital letters.
</em>
- <em>The sides of a triangle are written with lowercase letters.
</em>
- <em>The angles of a triangle are written similarly to the vertices.
</em>
Answer:
The end points of the triangle are called vertices.
They are labeled in capital letters.
The area of a trapezoid is calculated using the formula: 1/2(a + b)h. The diagram shows that base number one (a) is 8.5 dm and base number two (b) is 26.5 dm. The height is 9 dm. Substitute these values into the formula.
1/2(8.5 + 26.5) * 9, add 8.5 and 26.5 inside the parentheses.
1/2(35) * 9, you can now solve from left to right. Multiply 1/2 and 35.
17.5 * 9, multiply to get your final answer. The area of the trapezoid is C. 157.5 dm^2.
