Can a triangle have sides 150cm 10 cm and 10cm and what is the rule?

no because a²+b ²=c ².
Because 10²+10²=14.1
100+100=200
So you can't have 150 but you can have 200

By how much does the largest angle of a triangle differ from a right angle when its sides are 10cm 11cm and 15 cm?
Using the cosine rule gives the largest angle of the triangle as 91.04179885 degrees or 91.042 degrees rounded to 3 decimal places. So: 91.042-90 = 1.042 degrees
Perimeter of acute triangle?
There is no rule for the perimeter of an acute triangle. You simply need to add the sides.
What are the internal angles to 3 significant figures of a triangle when its perimeter is 150cm and its sides are in the ratio of 4 5 6?
82.8, 41.4 and 55.8 degrees The sides are 40cm, 50cm and 60cm so use the Cosine Rule to find the interior angles: Cos A = (b2+c2-a2)/(2bc) Change the formula to find the other angles
How and by its angles do you describe each triangle by its sides?
Equilateral triangle-All three sides are equal-All three angles measure 60 degreesIsosceles Triangle-Two equal sides-Two equal anglesScalene Triangle-Three unequal sides-No rule for angles (just have to add up to 180 degrees)
What is the rule for the lengths of the sides of a triangle?
The basic rule is that the sum of any two sides must be greater than the third. Then there are the sine and cosine rules which involve the lengths of the sides but also the angles.
What are the patterns in a pascal's triangle?
Pascal's rule for his triangle pattern is all the sides are ones

How do you solve perimeter of a triangle?
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.

The basic rule is that the sum of any two sides must be greater than the third. Then there are the sine and cosine rules which involve the lengths of the sides but also the angles.

What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
What is a rule for the 45-45-90 right triangle?
There is no single rule. It is a right angled isosceles triangle. Its long side (hypotenuse) is sqrt(2) times the short sides.
What is the third side of the triangle rule?
The sum of two sides must be greater than the third.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
How do you work out the hypoteneuse side of an isosceles triangle if the triangle is not right-angled and two of the sides and the angle between them are known?
Use the cosine rule: a2 = b2+c2 - 2bc*cos A An isosceles triangle has two equal sides.
