How do you make triangle in mswlogo?
First, do these commands : FD 100 RT 120 FD 100 RT 120 FD 100 Next, the the turtle is still present, so type HT in the box. And then you're done by getting a right sided equilateral triangle.
How many trapezoid in a triangle?
A triangle cannot be formed by any number of trapezoids. Every time a trapezoid is stretched across one side of a triangle, a smaller triangle similar to the first is formed by the part not covered by the trapezoid. Unless... the triangle was equilateral and the trapezoids were isoceles. You could fill the triangle with 3 trapezoids as follows: Use the longer 'bottom' edge of each trapezoid and the 'left' edge of the next trapezoid to make up the edge of the triangle. The shorter 'top' edge of the trapezoids touch the 'right' edge of the next trapezoid in the center of the triangle.
Are all equilateral triangles are similar?
DFN: we call a triangle equilateral if all sides of the triangle are the same length DFN:we call two triangles similar if corresponding angles are equal, and corresponding sides are proportional. First show that all corresponding sides are proportional: Consider a equilateral triangle with side lengths 1, all other equal lateral triangles sides can be expressed as S*(1), where S is some scalar. Hence all equilateral triangles sides are proportional to each other. Next, show that all corresponding angles are equal: The angle between two sides of a triangle is related to the length of the sides. These relationships are called sin, cos, and tan. Knowing that the cos(x), where x is one of the angles in the triangle, is the adjacent divided by the hypotenuse we see that cos(x)=(1/2)c/a, since a = c (because its equal lateral) we are left with cos(x)=(1/2) which means x = 60 degrees. this can be applied to all three angles, which shows that all three angles are 60 degrees. / \ / | \ a / | \ b /__ |__\ c We have now shown that all equal lateral triangles are similar because they all have proportional sides, and they all have equal angles.
What is the angles of a perfect scalene triangle?
The angles will differ from one to the next
Which comes next in the pattern of a horizontal line a L shape and a triangle a right triangle a square a rhombus or a vertical line?
a square
Wich is the next step in the following construction of an equilateral triangle?
The question isn't clear.
Show how to construct a 120 degree angle?
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
What will be the perimeter of an equilateral triangle inscribed in a circle of area154 sq.cm?
The formula for area of a circle is Area=pi*radius2 you know the area of your circle so now find the radius. 154 = pi*r2 r = 7 cm if you can imagine the equilateral triangle in the circle imagine that the radius touches the exact center of this triangle and can extend to one of the three points on the triangle. (this next part would be so much easier if i could draw you a picture). now, if you remember that an equilateral triangle has three angles that each measure up to 60 degrees. if you take the radius of the circle and draw a line from the center of the triangle to the tip of the triangle you will actually cut on of the 60 degree angles in half. this would now make you have an angle 30 degrees. if you do this same thing to another point you will notice you actually have another triangle inside this triangle. since all triangle angles add up to 180 degrees you know all three angles of this new triangle. (note: this new triangle is not an equilateral triangle). so this new triangle has an angle 30 degrees, 30 degrees, and 120 degrees. you can now use the law of sines to find out the length of one side of the equilateral triangle. if you have drawn your picture correctly then you will see that one side of the new triangle actually shares one side of the equilateral triangle. if you look at your new triangle their is only one side that is known a known quantity. this side is the side that is shared with the equilateral triangle. use the law of sines to figure out the length of this side... 7 / sin(30) = x / sin(120) x = 12.12cm you now know that one side of the equlateral triangle is 12.12cm. since there is three sides to the triangle the total perimeter of the equilateral triange is 12.12 times 3 your answer for the perimeter of the equilateral triangle is 36.36cm

How can you make 4 equilateral triangles from 6 equal length sticks or matches?
Make a Triangular Pyramid. Place three flat to form the first triangle, then make it into a pyramid with the remaining three. (It's a tetrahedron - a four-sided figure, and all sides are equilateral triangles.)

Can you draw an equilateral triangle using a straightedge and compass?
Yes, it is quite simple.Draw a straight line segment, AB. Put the compass point at A and open it so that the pencil point is at B. Then draw an arc. Next, without changing the compass setting move it to B and draw another arc to cut the previous arc at C. [Actually there will be two points, one on either side of AB.] Using the straight edge, join AC and BC. Then ABC is an equilateral triangle.
How do you make a triangle out of 3 trapezoids?
There is no combination of trapezoids which can form a triangle. well not exactly, if you have three " isoceles like trapezoid", then you can, provided, you are allowed to overlap. you should be able to figure it out now.... What if the triangle was equilateral and the trapezoids were isoceles? You wouldn't need the trapezoids to overlap. Use the longer 'bottom' edge of each trapezoid and the 'left' edge of the next trapezoid to make up the edge of the triangle. The shorter 'top' edge of the trapezoids touch the 'right' edge of the next trapezoid in the center of the triangle.
What is the side of the triangle next to the angle?
The side of the triangle next to the angle is called the adjacent side.
Why is there 360 degrees in a triangle?
There are 180 degrees in a triangle. Next question?
Where is the circumcenter of an obtuse triangle?
The circumcentre is outside the triangle - next to the longest line.
What are the Sides adjacent to the right angle of a triangle?
Adjacent means next to. So you're asking what sides of a triangle are next to the right angle of a triangle. That would be the 2 shorter sides of the triangle or 'legs' of the triangle. The hypotenuse (which is the longest side of the triangle) is directly across from the right angle.
