Gas prices rise as oil, a nonrenewable fuel source, becomes increasingly difficult to find and produce. Nonrenewable resources are used worldwide to create electricity, heat homes, power vehicles and manufacture goods.il, or petroleum, comes from the liquified, fossilized remains of plants and animals that lived hundreds of millions of years ago; once oil sources are depleted, they cannot be replaced. Oil is an energy source that the U.S. is very much dependent upon. It is used to create fuels, such as gasoline, diesel and jet fuel.
The isosceles trapezoid has one line of symmetry, the perpendicular bisector of the base. The scalene triangle has no lines of symmetry. The isosceles triangle has one line of symmetry, the perpendicular bisector of the base. The ellipse has two lines of symmetry, one along the major and one along the minor axis.he rectangle has two lines of symmetry, the perpendicular bisector of the longer sides, and the perpendicular bisector of the shorter sides. The circle has infinitely many lines of symmetry, any line going through the center. (Any diameter is a line of symmetry.) The parallelogram pictured has no lines of symmetry.
Asker's rating. Report Abuse. Isosceles triangle has one line of symmetry, equilateral have 3 lines of symmetry because they have 3 equal sides and a scalene has 3 different sides so no lines of symmetry.
