What else can I help you with?
Could 3 5 and 7 represent the length of the sides of a right triangle?
no it cannot represent as in angle triangle rule it doesnt prove that term
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 one geometry rule that the Greeks discovered do we still use today?
It is Pythagoras' theorem that is applicable to any right angle triangle.
What is the smallest angle of a right angle triangle when its hypotenuse is 7.4cm with one of its sides 4.6cm in length?
The smallest angle of the triangle is opposite to its smallest side which is 4.6cm and so by using the sine rule: A/a = B/b = C/b the smallest angle works out as 38.43 degrees rounded to two decimal places.
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
Where does Pythagoras's rule not work?
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)

What if two angles of a triangle are complemenatr what is the measure of the third angle?
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.

What is side A in triangle ABC rounded to the nearest hundredth if B is 35 and C is 21?
Not enough information has been given to work out side A such as any of its angles upon which the sine rule could have been used to find side A but if the given triangle is a right angle triangle then side A is 28 which conforms to Pythagoras theorem for a right angle triangle.
How many angle of a triangle?
there are 3 angles in a triangle which is mathematically true if you check in the math rule book and rule determined by Andres Schavascapel

What is the rule for finding the shorter side of a triangle?
A squared + B squared = c squared. c is across from the right angle and you subtract A from C and that's your answer
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.
Why is it impossible for a right triangle to have an obtuse angle?
because an obtuse ange has to be OVER 90 degrese. and a right angle is 90 degrese no matter what because a right angle is 90% and an obtuse is bigger than 90% it is impossible because a triangle only has three angles 1 angle is a right angle, 90 degrees another angle is an acute angle another angle is an acute angle an obtuse angle is an angle more than 90 degrees if you had an obtuse angle, then two of your angles would add up to 180 degrees already. it is a rule that the three angles of a triangle HAVE TO had up to 180 degrees exactly, so if you had an obtuse angle, the angles would add up to more than 180 degrees.
