What is the number of diagonals drawn from one vertex on a triangle?
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
How many lines of symmetry can be drawn in a scalene triangle?
None. If you put a line anywhere in a scalene triangle, the two sides would not be symmetrical because scalene triangle has all sides and all angles different.
How many lines of symmetry can be drawn in scalene triangle?
None. If you put a line anywhere in a scalene triangle, the two sides would not be symmetrical because scalene triangle has all sides and all angles different.
How may diagonals does a scalene triangle have?
A scalene triangle, like any other triangle, has zero diagonals. This is because a diagonal is drawn between two vertices that are not adjacent to each other. In a triangle, each vertex is adjacent to both others, so no diagonals exist.In general, for a polygon with n sides, for each vertex there are n-3 adjacent vertices (that is, all vertices excluding the vertex itself and its two neighbors). However, each diagonal is incident upon two vertices, so one must divide by 2. The number of diagonals is then n(n-3)/2. This does not depend upon the lengths of the sides of the polygon, only upon the number of sides.
Are the diagonals of an isosceles triangle congruent?
Yes, the diagonals of an isosceles triangle are congruent. This is because an isosceles triangle has two sides that are equal in length, which creates two congruent triangles when the diagonals are drawn.
How many right angled triangle are possible if two diagonals are drawn within a square?
4 because the diagonals bisect each other at 90 degrees
What does a scalene triangle look like?
A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted Triangle (Trigon) ABC.Scalene triangle is a triangle in which all the sides of the triangle will be unequal. The angles of triangle will be unequal. In the above triangle, the sides of the triangle are 8 cm, 10 cm, and 16 cm.The Scalene Triangle has no congruent sides. Each of the sides is different in length.The Acute Triangle has three acute angles (an acute angle measures less than 90°)Scalene triangles are unusual in that the are defined by what they are not. Most triangles drawn at random would be scalene. The interior angles of a scalene triangle are always all different. The converse of this is also true - If all three angles are different, then the triangle is scalene, and all the sides are different lengths.
What is a acute Scalene?
A scalene triangle is one where each side is a different length. Acute means that the largest interior angle of the triancle is less than 90 degrees A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments.
