Tangent Lines and Perimeters

Mr. Kenya Nola explains how to find the perimeter of polygons using tangent lines and the two tangents theorem. He provides examples with a triangle and a quadrilateral, emphasizing the congruence of tangent segments. The video concludes with the introduction of the term 'circumscribed' for polygons around circles.

What is the main goal of the video tutorial?

• To find the perimeter of polygons

• To find the area of polygons

• To find the angles of polygons

• To find the volume of polygons

What should you assume about lines that appear to be tangent?

• They are parallel

• They are perpendicular

• They are tangent

• They are bisectors

What does the Two Tangents Theorem state?

• Two tangent segments that intersect are congruent

• Two tangent lines are always perpendicular

• Two tangent lines are always parallel

• Two tangent segments that intersect are different

In the triangle example, what is the length of the segment calculated using the Two Tangents Theorem?

• 12 units

• 11.7 units

• 23.1 units

• 11.4 units

What is the total perimeter of the triangle in the example?

• 70.2 units

• 23.1 units

• 11.4 units

• 57.4 units

What is the length of the tangent segments in the quadrilateral example?

• 7 units

• 6.4 units

• 10 units

• 5.3 units

What is the total perimeter of the quadrilateral in the example?

• 70.2 units

• 57.4 units

• 23.1 units

• 11.4 units

What does the term 'circumscribed' refer to?

• A polygon with no relation to a circle

• A polygon outside a circle with tangent points

• A polygon inside a circle

• A polygon with equal sides

What should you not assume about segments in the examples?

• They are bisectors

• They are midpoints

• They are congruent

• They are tangent
