Glasses like this are called bi-focals. Bifocals
regular polygons
Nope
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
No, triangles with the same side lengths are always congruent.
True of False, any to parallelograms with the same side lengths have the same area?
Triangles are congruent if the lengths of their corresponding sides as well as the measures of their corresponding angles are the same.
If all of its sides are the same length its an equilateral triangle. If only two of its sides are the same length it is an isosceles triangle. If all the sides are different lengths it is a scalene triangle
They are the same for pairs of corresponding sides.
An isoceles triangle! It has two lengths the same!
Glasses are optics which are designed specifically for the owner. They correct the focal length of the light projected on the retina on the back wall of the eyeball. If your eyeball is not the same shape of depth as the person who owns the glasses then the image seen through them will appear to be out of focus to you. It is not wise to use anothers glasses since the muscles in your eye will attempt to correct the image and may strain them in doing so.
only if you can't see without the glasses. Glasses do not make you smarter, they just help you to see better. I would know i was getting the same grades i got be for i got my glasses I get the same grades still. HAHAHA!!!
Similar triangles means they have the same lengths OR the corresponding lengths have equal ratios.
