Isosceles
Correct
Two triangles.
Yes, since all the sides of a square are equal and the definition of an isosceles triangle is to have at least two congruent sides. The congruent triangles formed are 45-45-90 triangles, so the diagonal will be the longest side with the right angle formed where the two sides of the square meet.
One simple method is to measure the radius with a ruler then multiply it by 2 to get the diameter. The accuracy depends on how exactly you are measuring through the center.Geometrically accurate method is as follows:Draw a square within the circle so that each corner or apex of the square touches the circumference of the circle.Draw a straight line from one apex (corner) of the square to the opposite apex (corner) forming a diagonal of the that square.The diagonal of the square is the diameter of the circle.To countercheck the diameter measured, you can use the Pythagorean theorem on the two triangles formed by the diagonal of the the square.Caution: The square must be accurate to get the exact diameter of the circle.
Isosceles
True.
Correct
Two triangles.
The name of the shapes formed are triangles.
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
Two right angle triangles, normally scalene triangles. However, if the rectangle is for example a square, then it would be two isosceles triangles.

Yes, a diagonal of a parallelogram divides it into two congruent triangles. This is because the opposite sides of a parallelogram are parallel and congruent, so the two resulting triangles formed by the diagonal are mirror images of each other and thus congruent.
A diagonal line of a polygon is a line that joins any two vertices not already joined by a side.A polygon with n sides has n(n-3)/2 diagonals→ a quadrilateral with 4 sides has 4(4-3)/2 = 4 × 1 ÷ 2 = 2 diagonalQuadrilaterals include:Squares, rectangles, rhombuses, parallelograms, kites, trapezia (trapezoids).The diagonals of a quadrilateral divide the quadrilateral into 4 triangles. depending upon the quadrilateral some, or all of the triangles may be congruent.The properties of the diagonals of each quadrilateral are:square: equal and bisect each other at 90°; the triangles formed are all congruentrectangle: equal and bisect each other but not at 90°; the triangles formed are all congruentrhombus: not equal but bisect each other at 90°; the triangles formed are all congruentparallelogram: not equal but do bisect each other, but not at 90°; the triangles formed are congruent in (opposite) pairskite: perpendicular and the longer diagonal bisects the shorter diagonal; the triangles formed are congruent in (adjacent) pairstrapezium (trapezoid): only of equal length and bisect each other if it is an isosceles trapezium (trapezoid) and the triangles formed are congruent in (opposite) pairs; otherwise they are of differing lengths and just intersect each others and the triangles formed are non-congruent.
