Draw two line segments at a right angle, and add three more line segments to complete a closed figure.
Two lines that form a right angle are Perpendicular. This can be show by an upside down T.
This is not possible. If a triangle is a Right angled triangle then the sum of the two angles which are not right will be = 90 [Angle Sum Property] That's why you see.
Yes, AAA is a way to show that triangles are similar. Note, however, that AAA is not a way to show that triangles are congruent.
Without seeing the picture, I can't tell what's already known to be congruent, so there's no way I can figure out what 'else' is needed.
The Pentagon isn't in Washington DC, it's in Arlington, Virginia, but regardless of that, the pentagon is a five sided building with each side being 921 feet in length. 921 times 5 is 4605. The parameter of the pentagon is 4605 feet.
If you wan't to show that a pentagon has no right angles, then don't put any right angle signs in the figure.
A pentagon has 5 sides.
A pentagon is a 5 sided shape. Google pentagon and it will show you a picture.
yes
An underlined M is a concave pentagon. M (See link below)

An acute angle is a angle less than 90 degrees
A regular pentagon doesn't have any right angles ! See related link.
To show it is a right angle, and that it is perfectly square.
To show a right angle you have to mark the inside corner so that it looks like a square.
No, not through this browser.
if you are doing proof statements...there is converse which is where you flip the statement around so if the statement would be IF a angle measures 90 degrees, THEN the angle is a right anlge. The converse would be IF a angle is a right angle, THEN it is 90 degress. THE COUNTEREXAMPLE would be if the statement was false you would say or show a picture of something defining that statement
