A triangle with VERY round points is a circle.
There is no geometric term for a triangle with rounded points, but a triangle with rounded sides is known as a Reuleaux triangle. It is similar to the shape used for the piston in a rotary engine.
A triangle, but only if the line segments are straight.
right triangle
triangular polygon
The term 'equilateral' means having equal sides. For example, an equilateral triangle is a triangle with 3 sides all of equal length.
The abbreviation for triangle is "tri." In geometry, the term "tri" is commonly used to represent a triangle in equations, diagrams, and proofs. It is derived from the prefix "tri-" which means three, reflecting the three sides of a triangle.
There is no specific name in general. If the line segments are straight, then it is a triangle.
An isosceles triangle has two sides of equal length and the angles opposite those sides are also equal. The term "coplanar" means that four points lie on the same plane. In the context of an isosceles triangle, the three vertices of the triangle and any additional point (such as the midpoint of the base) can indeed be coplanar. Therefore, it is true that four points can be coplanar in relation to an isosceles triangle.
The term that describes such a triangle is "congruent." Two triangles are congruent if they have the same shape and size, meaning that one triangle can be transformed into the other through rotation, reflection, or translation. If a triangle is defined by specific conditions (such as side lengths or angles), no other triangle with different dimensions can satisfy those same conditions.
That figure is best described as a "triangle".
A triangle, but only if the line segments are straight.
The term "Bermuda Triangle" was popularized in the 1960s to describe the area in the western part of the North Atlantic Ocean where several aircraft and ships have disappeared under mysterious circumstances. The shape of a triangle was chosen to represent the geographic boundaries of this area. There is no particular reason why it is not called a circle, it was just a choice made by those who coined the term.
A trapezoid triangle is a misnomer, as it combines two distinct geometric figures: a trapezoid and a triangle. A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides, while a triangle is a three-sided polygon. If the term is used, it may refer to a triangle inscribed within a trapezoid or a specific configuration involving both shapes, but it is not a standard geometric term.
There is no synonym. Mathematics uses very specific words for fundamental terms.
The term for a large rounded articulating knob is "lunate."
A triangle with a square base is not a standard geometric term, but it can be described as a triangular prism if referring to a three-dimensional shape with a triangular top and a square base. If you mean a two-dimensional figure, it might be more accurately described as a right triangle or an isosceles triangle depending on the specific dimensions and angles. In general, the combination of a triangle and a square base does not have a specific name.
The Nth term for a triangle number is: 0.5n(n+1)
A triangle is a 3 sided polygon
