Which of these triangles appears to be congruentto any others shown here?
which pairs of triangles appear to be congruent
A heptagon can be divided into how many triangles by drawing all of the diagonals from one vertex?
A heptagon has seven sides, so when drawing diagonals from one vertex, it will create five triangles. This is because each diagonal drawn from a single vertex will create a triangle until it intersects the previous diagonal. Therefore, the number of triangles formed by drawing all diagonals from one vertex in a heptagon is five.
Which shape does not belong with the others rectangle square trapezoid or rhombus?
Trapezoid. The rectangle, square, and rhombus are all parallelograms. The Trapezoid is a solid: a prism of trapezium cross-section.
How many triangles are in an 11 sided polygon?
Any n-sided regular polygon, by joining a single vertex up to each of the others, will have a total of (n - 2) triangles inside. In this case, an 11-sided polygon will contain 11 - 2 = 9 triangles.
Is The area of a rectangle always greater than the perimeter?
To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.
What are formulas for area and perimeter?
Perimeter is the distance around the figure. Add all sides. Area depends on the figure. Triangle --- 1/2 bh Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.
Is triangle a symmetric figure?
It can be but it doesn't have to be. Some triangles are symmetrical and others aren't.
What 3D figure has eight triangles?
An octagonal pyramid has eight triangles on an octagonal base. An octahedron can also be made by putting a square pyramid on another inverted square pyramid. This shape has just eight triangles and no others.
Can Similar triangles improve your solving problem skills?
No, only your brain can. Similar triangles can be used to solve some problems but not others but it is for you to work out - using your brain - whether or not similar triangles are relevant and then to figure out how they might be used.
What is the internal angle of a hexagon?
120 degrees The way to figure any polygon is to draw diagonals from one of the vertexes to all the others and count the triangles. A 6 sided figure has 4 triangles. 4 times 180 = 720 total degrees. Divide that by 6 and you have 120.
What shape has diagonals bisect each other what is the shape called?
A rhombus satisfies this. Also a rectangle. And a square (which is both a rhombus and a rectangle). There may be others.
A heptagon can be divided into how many triangles by drawing all of the diagonals from one vertex?
A heptagon has seven sides, so when drawing diagonals from one vertex, it will create five triangles. This is because each diagonal drawn from a single vertex will create a triangle until it intersects the previous diagonal. Therefore, the number of triangles formed by drawing all diagonals from one vertex in a heptagon is five.
Are all triangle polygons similar?
A polygon is just a word used to describe any plane figure bounded by straight lines. A triangle is just one of many different polygons; others are a rectangle, pentagon, octagon etc. Triangles are said to be similar when they have the same shape but one is an enlargement of the other. The triangles must therefore be equi-angular and the ratios of corresponding sides have to be equal.
Which of these triangles appears to be congruentto any others shown here?
which pairs of triangles appear to be congruent
Is a triangle a symmetric shape yes or no?
Some triangles are symmetric, while others are not. All equilateral and isosceles triangles are symmetric.all triangles are symmetric.
Is a triangle symmetric?
'Isocoles' and 'Equalateral' triangles are, scalene, right angled, and obtuse triangles are not.
Can a triangle have perpendicular lines?
Right triangles do. Others don't.
