How does the measure of an angle help you classify shapes?
In triangles the angles can be all sorts of measurement but the three angles always add to 180 degrees. In quadrilaterals the angles usually measure to 90degrees in all four corners. But in things line trapezoids and parallelograms the angles differ. In a pentagon the angles are 120 degrees. All five of them.
How many acute angles in a square divided into four equal triangles?
An acute angle is less than 90 degrees. Dividing a square into four equal triangles would not have any acute angles since they would all be 90 degrees. A 90 degree angle is called a right angle.
How do you find an measure of an angle in a rectangle?
A rectangle is a quadrilateral (four sided shape) with four right angles. Therefore, the measure of every angle is 90 deg.
What is the sum of the interior angle of a twenty sided polygon?
(20-2)*180 18*180 3240 The way that I remember this is that a triangle, 3 sides, has one triangle in it. A four sided figure, if you draw one diagonal, has 2 triangles in it. So there are 2 less triangles in a figure than the number of sides. A triangle's interior angle measure is 180 degrees.
What are the four congruence theorem for right triangle?
four types aressssasrhsasa1.HyL Theorem (Hypotenuse-Leg) - if the hypotenuse and leg of one triangle is congruent to another triangle's hypotenuse and leg, then the triangles are congruent.2.HyA (Hypotenuse-Angle) - if the hypotenuse and angle of one triangle is congruent to another triangle's hypotenuse and angle, then the triangles are congruent.3.LL (Leg-Leg) if the 2 legs of one triangle is congruent to another triangle's 2 legs, then the triangles are congruent.4.LA (Leg-Angle) if the angle and leg of one triangle is congruent to another triangle's angle and leg, then the triangles are congruent.
