Can the lengths 9/11/13 make a triangle?

Can the lengths 9/11/13 make a triangle?

SOLUTION: Yes; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

How do you construct a triangle in Class 9?

Follow the given steps to draw a triangle with RHS property.

1. Draw the line segment AB, equal to the measure of hypotenuse side.
2. At one endpoint, say A, of line-segment measure the angle equal to 90 degrees and draw a ray, AR.
3. Measure the length of another given side and draw an arc to cut the ray AR at a point P.

How do you construct a triangle with sides 4cm 5cm and 6cm?

1. Draw base AB of side 4cm.
2. With A as centre , and 5cm as radius, draw an arc.
3. With B as centre , and 6cm as radius ,draw an arc.
4. Let C be the point where two points intersect.
5. Join AC and BC.

How do you draw a pentagon easily?

A direct method using degrees follows:

1. Draw a circle and choose a point to be the pentagon’s (e.g. top center)
2. Choose a point A on the circle that will serve as one vertex of the pentagon.
3. Draw a guideline through it and the circle’s center.
4. Draw lines at 54° (from the guideline) intersecting the pentagon’s point.

Can you construct a triangle that has side lengths 11cm 12cm and 15cm?

Yes, we can.

Does a triangle with side lengths 15 12 9 exist?

Therefore yes, it is a right triangle.

How do you draw a regular Pentagon and then a triangle of the same area?

Answer

1. Tan 36 = 2/h (Where h = apothem) h = 2/Tan 36.
2. = 2.75. Area = (½ x 4 x 2.75) x 5.
3. = 27.53 cm2. A triangle of the same area: Assume base of triangle = 4cm.
4. Area = 1/2bh. 27.53 = ½ x 4 x h. 27.53 = 2h. h = 13.8 cm.

What is construct triangle?

Triangles can be constructed using a ruler and a compass and even with the help of a protractor. A triangle has three sides, three vertices, and three angles. The sum of interior angles of a triangle is equal to 180°. This property is called the angle sum property of a triangle.

How do you construct a triangle like a triangle?

Construction Of Similar Triangles

1. If two triangles ∆ABC and ∆PQR are said to be similar triangles, then the following two conditions must be satisfied:
2. (i) The corresponding angles of the two triangles are equal.
3. i.e. ∠A = ∠P, ∠B = ∠Q, ∠C = ∠R.
4. (ii) Corresponding sides are in a ratio or proportion.

Can 4cm 5cm 6cm be the sides of a triangle?

Hence, the three sides will not form a right angle triangle.
