## In what way similarity of triangles is different from similarity of polygons?

They could be oriented or tilted differently though. For polygons (including triangles), similarity means that the corresponding angles are same. The converse is also true, that is, if the corresponding angles of two polygons are equal, then the two polygons are similar.

**What shapes always similar?**

Specific types of triangles, quadrilaterals, and polygons will always be similar.

**What is polygon exterior angles theorem?**

Polygon Exterior Angle Sum Theorem If a polygon is a convex polygon, then the sum of its exterior angles (one at each vertex) is equal to 360 degrees.

### What is exterior angle of a polygon?

If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. The sum of the exterior angles of a polygon is 360°.

**How can you describe any two polygons are similar?**

Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio (in other words, if they are proportional). Typically, problems with similar polygons ask for missing sides.

**How do you know when polygons are similar?**

Two polygons with the same shape are called similar polygons. The symbol for “is similar to” is ∼. Notice that it is a portion of the “is congruent to” symbol, ≅.

## What is an example of similar triangles or polygons that you may see in the real world?

Similar Triangles are very useful for indirectly determining the sizes of items which are difficult to measure by hand. Typical examples include building heights, tree heights, and tower heights. Similar Triangles can also be used to measure how wide a river or lake is.

**What are similar polygons?**

Two polygons with the same shape are called similar polygons. The symbol for “is similar to” is ∼. Notice that it is a portion of the “is congruent to” symbol, ≅. When two polygons are similar, these two facts both must be true: Corresponding angles are equal.

**What is the sum of exterior angle of polygon?**

360 degrees

Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees.

### What does the polygon angle sum theorem state?

The polygon exterior angle sum theorem states that “the sum of all exterior angles of a convex polygon is equal to 360°’.

**What is polygon exterior angle sum theorem?**

**How do you find the sum of exterior angles of a polygon?**

The sum of the exterior angles of a regular polygon will always equal 360 degrees. To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides or angles that the polygon has.

## What is the sum of the exterior of a polygon?

360°

If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .

**How does the concept of similar polygons can be applied in real life?**

Rectangular packing boxes, cheese, and butter blocks, bricks, and cereal boxes are cuboidal or rectangular prism figures which are appreciable as similar shapes in our daily life.
