## How do you prove Thales theorem in a triangle?

How to Solve the Thales Theorem?

- To prove the Thales theorem, draw a perpendicular bisector of ∠
- Let point M be the midpoint point of line AC.
- Also let ∠MBA = ∠BAM = β and ∠MBC =∠BCM =α
- Line AM = MB = MC = the radius of the circle.
- ΔAMB and ΔMCB are isosceles triangles.

**What is the converse of the triangle proportionality theorem?**

Triangle Proportionality Theorem Converse: If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

### What is the rule of Thales theorem?

In geometry, Thales’s theorem states that if A, B, and C are distinct points on a circle where the line AC is a diameter, the angle ABC is a right angle.

**What is basic proportionality theorem proof?**

Basic Proportionality Theorem states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points,then the line divides those sides of the triangle in proportion.

## What is Thales theorem one word?

Thales’ Theorem is a special case of the inscribed angle theorem, it’s related to right triangles inscribed in a circumference. In other words, the diameter of a circle always subtends a right angle to any point on the circle.

**What is another name of basic proportionality theorem?**

The intercept theorem, also known as Thales’s theorem, basic proportionality theorem or side splitter theorem is an important theorem in elementary geometry about the ratios of various line segments that are created if two intersecting lines are intercepted by a pair of parallels.

### What is SSS AA SAS?

AA-similarity. if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. SSS-similarity. if three sides of one triangle are proportional to three corresponding sides of another triangle, then the triangles are similar. SAS-similarity.
