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

Which 4 identical shapes put together will make triangles?
Four triangles, similar to the large one, but one third the size.
How many pairs of congruent triangles are formed diagonals of a rectangle?
Four.
Name all types of triangles for which the point of concurrency is inside the triangle?
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.
How can you remove 4 toothpicks from 16 toothpicks to get 4 congruent triangles?
Fuor toothpicks from 16 leave 12 which, by coincidence (?) is exactly enough for four equilateral triangles!

What is the name of the geometric solid with four faces that are congruent triangles?
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
