Answer:
Explanation:
To cut a rectangle of card in half diagonally to make two triangles, Ethan would follow a specific procedure. Let's break it down step by step:
Step 1: Start with a rectangle of card that measures 50 cm x 120 cm.
Step 2: Draw a diagonal line from one corner of the rectangle to the opposite corner. This line will divide the rectangle into two triangles.
Step 3: Use a ruler or straight edge to ensure that the line is straight and goes from one corner to the opposite corner.
Step 4: Carefully cut along the diagonal line using scissors or a craft knife. Make sure to follow the line precisely to create two separate triangles.
Step 5: After cutting, you will have two triangles. Each triangle will have one side that measures 50 cm and another side that measures 120 cm. The remaining side will be the diagonal line that was drawn and cut.
It's important to note that when cutting the rectangle in half diagonally, the resulting triangles will be right-angled triangles. This means that one of the angles in each triangle will be a right angle (90 degrees).
By following these steps, Ethan will successfully cut the rectangle of card in half diagonally to create two triangles. This process can be applied in various situations, such as creating models, constructing geometric shapes, or exploring the properties of triangles.
Now, to reinforce your understanding, here's a practice problem for you:
Practice problem: Ethan has a rectangle of card that measures 60 cm x 80 cm. He wants to cut it in half diagonally to create two triangles. What will be the measurements of each triangle's sides?
