What is the measurement of Angle J?*

So anytime you have same sides on both legs. You will have same angles for both that are not 90 degrees. So if all angles add up to 180. 180-90 = 90. 90/2 = 45 degrees

J = 45

Step-by-step explanation:

Since the two sides are the same, the base angles must be equal.  Since it is a right triangle, the two angles share 90 degrees

90/2 = 45

Each angle is 45 degrees

J = 45

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

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
