Step-by-step solution for: Area of a Triangle Worksheets
It looks like you've uploaded a worksheet titled "Area of Right Triangles – Show Your Work!" which includes several right triangles on a grid, and the task is to calculate the area of each triangle. Since I can't view images directly, I'll guide you through how to solve this type of problem step by step, assuming the image contains right triangles drawn on a grid.
---
The formula for the area of a right triangle is:
$$
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
$$
- The base and height are the two legs of the right triangle (the sides that form the right angle).
- You can measure these lengths using the grid (each square is typically 1 unit × 1 unit).
---
Let’s assume the worksheet has labeled triangles (like A, B, C, etc.) placed on a coordinate grid. Here's how to solve for each:
#### Example: Triangle A (yellow)
1. Identify the base and height:
- Count the number of units along the horizontal leg (base).
- Count the number of units along the vertical leg (height).
- For example, if base = 3 units and height = 4 units:
$$
\text{Area} = \frac{1}{2} \times 3 \times 4 = 6 \text{ square units}
$$
2. Write your answer in the table:
- Fill in the corresponding row with the calculated area.
Repeat this process for each triangle.
---
- Use the grid lines to count units accurately.
- Make sure the triangle is right-angled, so the two legs are perpendicular.
- If the triangle is rotated, rotate your thinking — find the two legs forming the right angle.

| Triangle | Base | Height | Area |
|---------|------|--------|------|
| A | 3 | 4 | 6 |
| B | 5 | 2 | 5 |
| C | 6 | 4 | 12 |
| D | 2 | 3 | 3 |
> Note: These are hypothetical values. Replace them with actual measurements from your image.
---
For each triangle, write:
```
Triangle A:
Base = 3 units
Height = 4 units
Area = ½ × 3 × 4 = 6 square units
```
---
Since I can’t see the actual image, please provide:
- The coordinates or dimensions of each triangle (e.g., “Triangle A has base 3 and height 5”)
- Or describe the shapes and their positions on the grid
Then I can give you exact answers and show the full work!
But based on typical worksheets like this, here’s what you should do:
✔ Measure base and height for each triangle
✔ Plug into the formula
✔ Write down the area
✔ Show your calculation steps
Let me know if you’d like help with specific triangles!

📏 Tips for Measuring on Grids
- Use the grid lines to count units accurately.
- Make sure the triangle is right-angled, so the two legs are perpendicular.
- If the triangle is rotated, rotate your thinking — find the two legs forming the right angle.
