How can you use a right angle to decide to name another angle?
If the angle is larger than a right angle it is obtuse
How can you use a right angle to determine the classification of another angle?
An acute angle is smaller than a right angle.An obtuse angle is larger than a right angle.^_^
How do you measure and classify angles?
Use a protractor and they are classified as follows:- Acute angle: which is greater than 0 but less than 90 degrees Right angle: which is 90 degrees Obtuse angle: which is greater than 90 but less than 180 degrees Reflex angle: which is greater than 180 but less than 360 degrees
What are four ways you can prove two right triangles are congruent?
1. The side angle side theorem, when used for right triangles is often called the leg leg theorem. it says if two legs of a right triangle are congruent to two legs of another right triangle, then the triangles are congruent. Now if you want to think of it as SAS, just remember both angles are right angles so you need only look at the legs.2. The next is the The Leg-Acute Angle Theorem which states if a leg and an acute angle of one right triangle are congruent to the corresponding parts of another right triangle, the two right triangles are congruent. This is the same as angle side angle for a general triangle. Just use the right angle as one of the angles, the leg and then the acute angle.3. The Hypotenuse-Acute Angle Theorem is the third way to prove 2 right triangles are congruent. This one is equivalent to AAS or angle angle side. This theorem says if the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and an acute angle of another right triangle, the two triangles are congruent. This is the same as AAS again since you can use the right angle as the second angle in AAS.4. Last, but not least is Hypotenuse-Leg Postulate. Since it is NOT based on any other rules, this is a postulate and not a theorem. HL says if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
What is used to draw right angles?
I generally use a pencil and ruler. To construct the right angle to draw it I also use compasses. To measure the right angle to draw it I also use a protractor.
How can you use a right angle to decide to name another angle?
If the angle is larger than a right angle it is obtuse
How can you use a right angle to decide how to name another angle?
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;

How can you use a right angle to determine the classification of another angle?
An acute angle is smaller than a right angle.An obtuse angle is larger than a right angle.^_^
How do you use a right angle to determine the classification of another angle?
YOU can use a right angle by making it small to make it acute or you can make it big so it is obtuse
How do you use a right angle to decide how to name another angle?
You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
How can you use right angle to decide how to name another angle?
A right angle is 90 degrees if an angle is wider than 90 it is obtuse if it is less than 90 it is an acute angle.
How do you find the measures of a right angle with length and width shown?
A right angle is always 90 degrees. Another Answer:- If you mean the length of the hypotenuse then use Pythagoras' theorem which is applicable to right angle triangles
How can you use a right angle to determine the classiacation of another angle?
If the other angle is smaller than the right angle, it is an acute angle.If the other angle is the same as the right angle, it is a right angle.If the other angle is bigger than the right angle but smaller than two right angles, it is an obtuse angle.If the other angle is the same as two right angles, it is a straight angle.If the other angle is bigger than two right angle but smaller than four right angles, it is a reflex angle.After four right angles, the other angle starts back at being an acute angle.
If you have the hypotenuse and another side of the right angle how do you find the other right angle side?
you can take this fomula : a2 + b2= c2 and then use algebra to get a 2 =c2-b2
How do you measure and classify angles?
Use a protractor and they are classified as follows:- Acute angle: which is greater than 0 but less than 90 degrees Right angle: which is 90 degrees Obtuse angle: which is greater than 90 but less than 180 degrees Reflex angle: which is greater than 180 but less than 360 degrees
