What do diagnal mean?
Diagonal is a straight line through a figure from one corner to another corner, for example, the diagonal divided the square into two triangles.
A line segment connecting two vertices of a polygon?
A line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
How many vertices does a pentagon prism have?
A pentagonal prism has 10 vertices because there are 5 points on one side and 5 on the other. Note: another word for vertices is corners. A pentagonal prism has ten vertices. 5*2=10 :D 10
What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
How do you make a concave hexagon from 4 triangles?
Put four equilateral triangles so that each one of them has a vertex at a single point and the triangles abut one another. The shape will be 4/6 (= 2/3) of a regular hexagon.
How many triangles can be constructed if 3 sides are given?
1 Another Answer: 5 different types which are scalene, obtuse, right angle, isosceles and equilateral
Are vertices edges?
No. Edges join vertices; or, put another way, edges meet at vertices.
Can 9 toothpicks s be used to form 4 congruent triangles?
Yes. Make one triangle using hree matches. Underneath the two vertices at the base of this triangle, make another two triangles, using six more matches. You will find that there is an inverted triangle in the middle - the fourth.
What do diagnal mean?
Diagonal is a straight line through a figure from one corner to another corner, for example, the diagonal divided the square into two triangles.
Is there Another name for a small corner?
the answer is vertices e.g a restangle has 4 vertices
Which shape is a decagon?
A plane (2-dimensional) shape whose boundary consists of ten straight lines that do not cross one another but meet pairwise at ten vertices..
What are two non consecutive vertices?
Vertices that are not next to one another. There are none in a triangle. In a quadrilateral, they would be the opposite vertices.
The diagonals of a square are perpendicular Explain?
A square is a plane (flat) shape whose boundaries are four straight lines of equal length such that these lines meet, in pairs, at four points (vertices). At these vertices they form angles of 90 degrees. The diagonals of the square are straight lines joining opposite vertices. These diagonals meet one another. The given statement means that the angles formed at the crossing points of the diagonals measure 90 degrees.
A vertex is another word for?
a vertices
What is a triangular based prism?
A triangular based prism has 5 faces, 9 edges and 6 vertices
How many vertices does a triangle have?
3. Vertices is another word for angles.A triangle has three sides and therefore three vertices, or angles. Vertices are corners, so a triangle has three corners, thus three vertices.3Vertices is another term for angles.three 3; a vertice is where the two lines intersect A triangle has 3 vertices. It also has three angles and sides.A triangle has 3 vertices at each of its 3 corners
How many triangles does a hepagon have?
The word is heptagon. A heptagon has 7 sides and 7 corners. If you join corners by straight lines from one corner to another corner you will find 5 triangles, but if you join all corners to a point in the centre you will find 7 triangles. The Heptathlon in athletics is a contest in which the participants must compete in 7 different athletic forms of athletics.
