Is AAA theorem describes congruence of all three sides in corresponding triangles SSS postulate describes congruence of all three angles in corresponding triangles a true statement?
true
Are all right triangles equilateral triangles?
no. In fact a right angled triangle cannot be equilateral. An equilateral triangle is also equiangular: that is, all its angles are equal. The sum of all three angles of a [plane] triangle must be 180 degrees and so they cannot be 90 deg each.
Are all triangles semmetrical?
No. But all isosceles triangles and equilateral triangles are.
Is it false an acute triangle is always equilateral?
Yes it is correct that the statement is false. All equilateral triangles are acute, because all three angles are less than a right angle (90°). There are an infinite number of cases of acute triangles which are not equilateral.
Are all equilateral triangles also isoscelles triangles?
Yes. But not all isosceles triangles are equilateral.
Is all squares can be cut in half to make 2 congruent triangles a generalization?
no its an emphatic statement all squares can be cut in half to make 2 congruent isosceles right triangles is perhaps as general a statement as is possible
Do Quadrilateral tessellated?
No, we did a maths topic on tessallating quadrilacterals and we proved that not all do! hexagons tessalate and squares also triangles
Some rectangles cannot be split into two triangles?
Not true because all quadrilaterals contain 2 triangles
Is AAA theorem describes congruence of all three sides in corresponding triangles SSS postulate describes congruence of all three angles in corresponding triangles a true statement?
true
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
What CANNOT be used to prove triangles congruent ASA. SSS. SAS.?
All three of those CAN .
Are all equilateral triangles acute triangles?
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.

Yes it is correct that the statement is false. All equilateral triangles are acute, because all three angles are less than a right angle (90°). There are an infinite number of cases of acute triangles which are not equilateral.
Are all triangles polgons?
yes. all triangles.
