The total number of propositions in the elements are ______.

What country does Euclid belong?

Euclid stated that all right angles are equal to each other in the form of ______.

 It is known that if $$x+y\ =10\$$ then  $$x+y+z=10+z.$$  The Euclid's axiom that illustrates this statement is ______.

Euclid's fourth axiom says that everything equals itself.

The Euclidean geometry is valid only for figures in the plane.

Pyramid is a solid figure, the base of which is a triangle or square or some other polygon and its side faces are equilateral triangles that converges to a point at the top.

In geometry, we take a point, a line and a plane as undefined terms.

If the area of a triangle equals the area of a rectangle and the area of the rectangle equals that of a square, then the area of the triangle also equals the area of the square.

Euclidean geometry is flat so its curvature is zero.

The negatively curved non-Euclidean geometry is called _____________

Spherical geometry is called ____________ geometry

The sum of the angles of a triangle is less than 180 degrees in _______________ geometry.

The sum of the angles of a triangle is equal to 180 degrees in _______________ geometry.

Given a straight line and the point not on the line, there are no straight lines through the point parallel to the original line. This is true in _______ geometry.

Parallel lines intersect.

Euclidean geometry has ______ parallel line/s through any given point not on a line

The Elements is a mathematical treatise consisting of how many books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt ?

According to Euclid's Postulate, how many lines can pass from two distinct points?

According to Euclid's Postulate, how many lines can pass from one point?

Things which are equal to the same thing are equal to each other.

Euclid's First Postulate tells:

Who was the father of Geometry?

A geometric structure that extends the concept of a plane.

He is known as the "Great Geometer" on the basis of his text Conic Sections, an eight-"book" (or in modern terms, "chapter") series on the subject.

He was the father of Algebra, who is he?

A plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

It is a mathematical statement that is proved using rigorous mathematical reasoning.

Statement that assumed to be true without proof.

In geometry, how large is a point?

According to Thales' theorem

The legs of a right triangle are represented by a and b, and the hypotenuse of the right triangle is represented by c. Which equation represents the Pythagorean Theorem?

Which of the following used geometry to construct a mathematical model of the solar system as a response to Plato's challenge to his students about retrograde Motion?

Which is not one of Euclid’s postulates?

Which of the following needs a proof?

If $$x\ +y=7$$   and $$xy\ =5$$  , what is $$x^3+y^3$$  ?
