They're both acute angles.

These are both 90 degree angles

And they both have 90 degree angles

These can both be 30 degree angles.

Look at things from all angles.

That'll only be true if both of those angles were 90 degrees.

One angle, two angles, three angles, and four angles.

Anyway, so we figured out that both digital warheads were actually aiming at one and the same target, but from different angles.

I've got angles, lots of angles.

The distinction can be examined from different theoretical angles.

Both of those are the sides opposite the right angles of these 2 simlar triangles,

Angles 3 and 4 are supplementary angles.

I wanted to introduce you to are acute angles, right angles, and obtuse angles.

Angles

Angles

I can look at it from multiple viewpoints and angles.

Find yourself somewhere else... ...and catch life from new angles.

The cool thing is, this does it from all angles.

We know that angle CBE, and we know that angle DBC are supplementary they are adjacent angles and their outer sides, both angles, form a straight angle over here.

So angles 3 and 4, they're actually opposite angles.

So just there we know that all of the angles in both of the triangles are congruent.

God's greetings. We're going to discuss this issue from two angles

Vertical angles.

corresponding angles.

Vertical angles

They are opposite angles or, as they say, vertical angles.

Now let's think about the supplementary angles. so supplementary angles

And in order for both of these to be perpendicular those would have to be 90 degree angles.

Complementary angles are two angles that add up to 90 degrees, and supplementary angles add up to 180 degrees.

And I'll talk about more types of angles in the next video, but if an angle is less than 90 degrees so for example both of these angles that we started our discussion with are less than 90 degrees we call them acute angles.

If two supplementary angles are equal, the angles each measure 90.

Now, the next set of equal angles to realize are sometimes they're called vertical angles, sometimes they're called opposite angles.

They're supplementary angles.

Alternate interior angles

And we see the angles of the rings at different angles, there.

Then everything else proves out just through opposite angles and supplementary angles.

We know that two angles are the same as two other angles.

So from that we can deduce that all the angles are the same.

So corresponding angles let me write these these are corresponding angles are congruent.

Opposite angles are congruent.

Vertical angles are congruent.

Corresponding angles are congruent.

These are equal angles.

Corresponding angles are equal.

They are vertical angles
