## Is a circle straight or curved?

A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its centre.

## What is a shape with a curved side called?

Two-dimensional curved shapes include circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments.

## Can a straight line be a curve?

If a point moves in only one direction, we get a straight line. A line that is not straight is a curved line. If a point does not move in one direction, we get a curve.

## Which curve can also be a straight line?

Transcendental Curve – This curve is different from the algebraic curve. This curve might have many intersecting points which will be straight. These might also have an infinite number of inflexion points.

## Which tool is used to type text in MS Paint?

While typing text in the Drawing area of MS Paint, a Text Tools tab appears on the Ribbon. With the help of its Font group, you can change the font, font size, and font style of the text. You can also change the color of your text in MS Paint. But, for doing all this, you first need to select the text.

## What program is used to colorful drawings?

Tux Paint is a drawing program used to draw and colour pictures. It is very simple and easy to use software with many interesting features.

## Can curved lines parallel?

Yes, lines that are curved on the surface of a hyperbolic object (like a sphere or an incomplete sphere) can be parallel (the distance between each point on them stays the same).

## Are all parallel lines straight?

Parallel lines are always the same distance apart, which is referred to as being “equidistant”. For our purposes, parallel lines will always be straight lines that go on indefinitely. The parallel lines may be horizontal, vertical or slanted. A transversal is a line that intersects two or more lines in the same plane.

## Do parallel lines meet in infinity?

Geometric formulation In projective geometry, any pair of lines always intersects at some point, but parallel lines do not intersect in the real plane. The line at infinity is added to the real plane. This completes the plane, because now parallel lines intersect at a point which lies on the line at infinity.

## Where are parallel lines used in real life?

Parallel line examples in real life are railroad tracks, the edges of sidewalks, marking on the streets, zebra crossing on the roads, the surface of pineapple and strawberry fruit, staircase and railings, etc.
