(i) Find polar coordinates (r, θ) of the point, where r > 0 and 0 ≤ θ < 2π. (r, θ) =
(ii) Find polar coordinates (r, θ) of the point, where r < 0 and 0 ≤ θ < 2π. (r, θ) =

The answer is below

Step-by-step explanation:

A point in the coordinate plane can either be represented using the Cartesian form or the polar corm. The Cartesian form is represented as (x, y) where x and y are the horizontal and vertical coordinates while the polar form is represented as (r, θ), θ is the angle and r is the length.

Conversion of (x, y) to (r, θ) is:

a) (3, 4)

(3, 4) = (5, 0.296π)

b) (1, -3)

(3, 4) = (√10, 1.6π)

answer: idk

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
