yes
False because although the angles are the same the sides are proportional by ratio to each other.
They are triangles whose three sides are equal in length and whose three interior angles are equal in measure.
The question is a little confusing. If the floor is level you just put the bottom of the sliding glass door track on the floor. With the stationary section of glass in place the one side of the door should now be quite plumb and all you have to do is attach that part of the frame to the house. On the other hand, if you are asking about a door that is already installed and are wanting to plumb the slider, there should be two screws near the bottom of the door sides and two screws near the top. In order to turn the bottom screws it may be necessary to relieve pressure from the top screws and slightly lift the bottom of the door. Adjust the door so that it is parallel to either the stationary glass or the side frame, whichever side has the locking mechanism. LEVEL equalls left to right.....so place door in a bed of silicone greater than the amount the existing floor is out and shim the appropriate side up until the top of door from left to right is level PLUMB is vertical....... top to bottom and left to right with in one side of the jamb;;;jamb must be plumb in both direction and on both sides of jamb within a straight lin of itself for it to be SQUARE....
A square! The sides are all the same length and measure.
When measuring an angle you have to measure the sides using a protractor.
The area of a hexagon with sides that measure 20cm is approximately 1039.23cm2
Triangle
There cannot be a proof because the statement is not true. Nowhere does the statement say that the sides are straight.
It is what you get in an inference, after negating both sides. That is, if you have a statement such as: if a then b the inverse of this statement is: if not a then not b Note that the inverse is NOT equivalent to the original statement.
It is an equilateral triangle
