Geometry help! Please prove the following is a right- isosceles triangle, show all steps. (30 pts!!)

To prove that the triangle is a right- isosceles triangle, prove that

- There is a right angle in the triangle

- Two sides of the triangle are equal in length

Another way to prove that angle YXZ is a right angle is to calculate the length of XY, XZ and YZ using the distance formula. Then show that (YZ)² = (XY)² + (XZ)².

By the inverse of Pythagoras' Theorem, ∡YXZ is a right angle.

*The product of the gradients of 2 perpendicular lines= -1.

Please see the attached pictures for full solution.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
