The word "isosceles" refers to a triangle with two equal sides. The antonyms for the word "isosceles" could be "scalene," which refers to a triangle with no congruent sides, or "equilateral," which refers to a triangle with three congruent sides. These two words have the opposite meaning of "isosceles" because they indicate a triangle with different side lengths than an isosceles triangle. The term "isosceles" comes from the Greek word "isoskeles," which means "equal legs." By understanding the antonyms of a word like "isosceles," one can get a better understanding of the different properties of shapes and how they are described in mathematical terms.

Famous quotes with Isosceles

• Multiple-prism arrays were first introduced by Newton (1704) in his book In that visionary volume Newton reported on arrays of nearly isosceles prisms in additive and compensating configurations to control the propagation path and the dispersion of light. Further, he also illustrated slight beam expansion in a single isosceles prism.

• In geometry the following theorems are attributed to him [Thales]—and their character shows how the Greeks had to begin at the very beginning of the theory—(1) that a circle is bisected by any diameter (Eucl. I., Def. 17), (2) that the angles at the base of an isosceles triangle are equal (Eucl. I., 5), (3) that, if two straight lines cut one another, the vertically opposite angles are equal (Eucl. I., 15), (4) that, if two triangles have two angles and one side respectively equal, the triangles are equal in all respects (Eucl. I., 26). He is said (5) to have been the first to inscribe a right-angled triangle in a circle: which must mean that he was the first to discover that the angle in a semicircle is a right angle. He also solved two problems in practical geometry: (1) he showed how to measure the distance from the land of a ship at sea (for this he is said to have used the proposition numbered (4) above), and (2) he measured the heights of pyramids by means of the shadow thrown on the ground (this implies the use of similar triangles in the way that the Egyptians had used them in the construction of pyramids).
