Types of Triangles: By Sides: Isosceles- 2 congruent sides Scalene- no congruent sides Equilateral- 3 congruent sides By Angles: Acute- angles measuring less than 90° Obtuse- one angle measuring more than 90° Right- one angle measuring exactly 90° Equiangular- all angles measuring exactly the same- same as equilateral triangle
A tetrahedron has four equilateral triangles as sides
Four triangles, similar to the large one, but one third the size.
No, two equilateral triangles do not make a square. A square has four equal sides and four right angles, while an equilateral triangle has three equal sides but three angles that add up to 180 degrees. When two equilateral triangles are put together, they do not form a shape with four equal sides and four right angles, which is the defining characteristic of a square.
Four.
The answer depends on what point of concurrency you are referring to. There are four segments you could be talking about in triangles. They intersect in different places in different triangles. Medians--segments from a vertex to the midpoint of the opposite side. In acute, right and obtuse triangles, the point of concurrency of the medians (centroid) is inside the triangle. Altitudes--perpendicular segments from a vertex to a line containing the opposite side. In an acute triangle, the point of concurrency of the altitudes (orthocenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Perpendicular bisectors of sides--segments perpendicular to each side of the triangle that bisect each side. In an acute triangle, the point of concurrency of the perpendicular bisectors (circumcenter) is inside the triangle, in a right triangle it is on the triangle and in an obtuse triangle it is outside the triangle. Angle bisectors--segments from a vertex to the opposite side that bisect the angles at the vertices. In acute, right and obtuse triangles, the point of concurrency of the angle bisectors (incenter) is inside the triangle.
There are four different types of triangles. They include the isosceles triangle, equilateral triangle, scalene triangle and obtuse triangle. Triangles are used in geometry.
there are more than four: equilateral, right, obtuse, acute, scalene

The four different types of internal forces are tension (stretching force), compression (squashing force), shear (sliding force), and torsion (twisting force).
Octal, binary, duodecimal, and decimal, to name but four.
Squares have four sides, triangles have three.
