We come down at a 45 degree angle.

Let's say we go up at a 45 degree angle.

You can see the Lhotse face is in profile, it's about a 45 degree angle.

So that is a 90 degree angle, a 90 degree angle and that is a 90 degree angle over there

You can see the orange line leaving the desert floor at about a 45 degree angle there.

They have 90 degree angle here and they have 90 degree angle there

Locate the base so the ball arm is at a forty five degree (45 ) angle to the T slots

Maybe I have really good slingshot and I would sling something super fast at maybe a 45 degree angle.

This function transforms a radian angle to a degree angle.

This function transforms a degree angle to a radian angle.

Its going to be hit at a 45 degree angle at some velocity. This is that vector right over here.

The only way that this would be equal to 180, angle 3 plus angle 4, is if angle 4 were a 90 degree angle, and angle 3 were also a 90 degree angle.

We have a 92 degree angle, we have a 29 degree angle and the other one is 59 degrees.

Rather, he is entering the water at a 45 degree angle with his forearm, and then propelling himself by streamlining very important.

This is a 90 degree angle here.

They both have a 90 degree angle.

So we have a 90 degree angle.

And this is our 90 degree angle.

At the approximate angle of 45 degrees.

This is a 90 degree angle right here.

Make a V with a 60 degree angle.

This is the 90 degree angle right here.

This is clearly a right angle, or a 90 degree angle right over here.

This is a perfect 90 degree angle by nature.

So this has to be a 30 degree angle.

It intersects this base at a 90 degree angle

A Selectric switch has a similar design, but the contacts on the wires are skewed, often at a 45 degree angle, rather than being lined up.

They tell us that this is a 60 degree angle.

So we know that this is a 90 degree angle.

The ladder makes a 53 degree angle with the wall.

So that means that they intersect at a 90 degree angle.

A protractor is kinda like a 180 degree Angle A Tron.

Perpendicular lines are lines that intersect at a 90 degree angle.

This 90 degree angle kind of opens into this longest side.

Well the question mark angle let's call it x the question mark angle plus the 60 degree angle, they go halfway around the circle.

You can see the Lhotse face is in profile, it's about a 45 degree angle. It takes two days to climb it, so you put the camp halfway through.

So if we see a triangle that is a 90 degree, 45, and 45 like this,

This is, I call it the 30 degree side, it's opposite the 30 degree angle, or it's the shortest side.

And you can see from our measure right over here that that gives us a 90 degree angle, which is a very interesting angle that shows up many times in geometry and trigonometry, and there's a special word for a 90 degree angle it is called a right angle.

I have a batter who hits a ball, and they hit a ball right when it's 1 meter above home plate and they hit it at the perfect 45 degree angle, the perfect angle you need to have the optimal carrying distance.

This is a 90 degree angle, they do this little square thing there.

We could say this angle here is supplementary to this 122 degree angle, right, so it has to add up to 180.

And in all cases, the hypotenuse is the side opposite the 90 degree angle.

So the way I drew it right here, this is our 90 degree angle.

You see the diagonals intersect at a 90 degree angle so we've just proved
