Oh, dude, a cylinder has infinitely many lines of symmetry. Yeah, that's right, infinitely! So, like, you can keep turning it and it'll look the same from all angles. It's like the gift that keeps on giving... symmetry!
For an equilateral triangle, there are three axes of symmetry. A plane figure is symmetrical about the line l if, whenever P is a point of the figure, so too is P', where P' is the mirror-image of P in the line l. The line is called a line of symmetry (or axis of symmetry), and the figure is said to be a symmetrical by the reflection in the line l. An equilateral triangle with reflection symmetry has two halves that are mirror images of each other. If the shape is folded over its line of symmetry, the two halves of the shape match exactly. So, we can say that the two halves of an equilateral triangle are matched exactly only when its shape is folded over the lines of symmetry that passes through their vertixes and the midpoint of its sides. Thus, an equilateral triangle has three lines of symmetry, and three angles of rotation. If you rotate any shape a full turn, it will look like it did before you rotated it. When you rotate a shape less than a full turn about its center point and it looks exactly as it did before you rotated it, it has rotation symmetry. In an equilateral triangle there are three places in the rotation where the triangle will look exactly the same as its starting position. If we turn the triangle one third of a full turn (60 degrees), the vertex 1 will be at position 3, vertex 2 will be at position 1, and vertex 3 will be at position 2, and the triangle will look like its starting position.
Well, honey, a right triangle does not have rotational symmetry because if you try to rotate it by any angle other than 90 degrees, it won't look the same. So, unless you're planning on spinning that triangle like a disco ball at a 70s party, you won't find any rotational symmetry there.
It looks like a 3-D triangle.
It is a median.

Unless the rectangle is a square, it only has two lines of symmetry. Please refer to the Related Link below to see diagrams of both rectangles and squares with lines of symmetry drawn. The images are near the bottom of the page.

No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
Real-life objects that have three lines of symmetry are equilateral triangles, certain types of stars (such as a six-pointed star), and certain types of flowers (like a trillium). These objects have rotational symmetry of order three, meaning they can be rotated by 120 degrees and still look the same. The three lines of symmetry intersect at angles of 120 degrees, dividing the object into three equal parts.
It will look like a right angle triangle with a 90 degree angle and two 45 degree angles and will have one line of symmetry
