Maths Practical Geometry part 4 (Draw Triangle : Side Side Side) CBSE Class 7 Mathematics VII

## TL;DR

Learn how to draw a triangle when given the lengths of all three sides.

## Key Insights

• 🔺 Drawing a triangle with given side lengths involves drawing one side and using a compass to create arcs from the remaining two points.
• 🫠 The intersection of the arcs determines the position of the third vertex.
• 🙃 Isosceles triangles have two sides of equal length.
• 😷 The four-step learning process offered by Exam For Your Calm includes video lessons, question asking, note reference, and free online tests.

### Q: How do you draw a triangle with given side lengths?

To draw a triangle with given side lengths, start by drawing one side of the triangle. Then, use a compass to draw arcs from the other two points at distances equal to the lengths of the remaining sides. Connect the intersection point of the arcs to the original points to complete the triangle.

### Q: What is the concept behind drawing a triangle with given side lengths?

The concept is to use the properties of a compass to create arcs at specific distances equal to the side lengths. The intersection of these arcs helps determine the position of the third vertex, thus forming the triangle.

### Q: How can a compass be used to draw arcs at specific lengths?

By adjusting the opening of the compass to match the desired length on a ruler, you can ensure that the arcs drawn accurately reflect the given side lengths of the triangle.

### Q: What type of triangle is formed when two sides have equal lengths?

A triangle with two equal sides is called an isosceles triangle. This type of triangle can be identified when two sides of the triangle have the same length.

## Summary & Key Takeaways

• The video explains how to draw a triangle when the lengths of all three sides are given.

• Step 1: Draw one side of the triangle, such as BC.

• Step 2: Use a compass to draw arcs from points C and B at distances equal to the lengths of sides AC and AB, respectively.

• Step 3: The triangle is formed by connecting the intersection point of the two arcs with points B and C.
