You write the height. Draw as dashed line segment, which is perpendicular to the base, from the top vertex down to the base (or a dashed line extended from the base for an obtuse triangle). Put a right-angle symbol (small square) where this line segment intersects the base)

How do you draw the altitudes of a triangle?
hoe can we draw an altitude
How do you find the altitude outside of a triangle?
The altitude of a triangle is the distance from the line containing the base to the vertex. Draw the base and continue on outside of the triangle. Measure perpendicular from that line to the vertex.
What is the equidistant of a triangle?
is the altitude of a triangle
Can the altitude of a triangle fall out the triangle?
Yes its perpendicular height or altitude is sometimes calculated out side the triangle depending on its shape.
Who many in a triangle altitude?
A triangle has three altitudes.

How you can draw a altitude with isosceles triangle?
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Draw a triangle where the altitude is a side of the triangle?
Any right triangle resting on a leg.
How do you find the altitude outside of a triangle?
The altitude of a triangle is the distance from the line containing the base to the vertex. Draw the base and continue on outside of the triangle. Measure perpendicular from that line to the vertex.
Is an altitude ever outside a triangle?
Sure. If one of the base angles is more than 90 degrees, then the altitude (height) is outside the triangle. Yes. This only occurs with an obtuse triangle. Because an altitude is a line drawn from a vertex to the opposite side and is perpendicular with that opposite side, it can only occur if it is outside the triangle. Look at the triangle in related links. If you look at the vertex on the top, the only way to draw the altitude would be to draw outside the triangle.
In a right triangle when you draw an altitude to the hypotenuse are the triangles ever similar?
Only if the angles of the triangle are 90, 45, and 45.
Is the altitude of a triangle perpendicular?
The altitude of a triangle is measured perpindicular to its base.
What is the equidistant of a triangle?
is the altitude of a triangle
How do you calculate the altitude of a triangle?
Let the given area is 10cm. Base of the triangle is 4 cm. altitude of triangle=? Area= 1/2 x Base x altitude 10= 1/2 x 4x altitude 10=2 x altitude 10/2= altitude 5= altitude Hence, altitude of the triangle is 5 cm.
How you can find the orthocentre of a triangle?
Draw two altitudes: an altitude is a straight line from a vertex to the opposite side. The three altitudes of a triangle meet at the orthocentre, but two are enough to determine the point.
The perimeter of an equilateral triangle is 32centimeters find the length of an altitude of the triagle to the nearest tenth of a centimeter?
Since an equilateral triangle has three congruent sides (and 3 congruent angles, each of 60⁰), the length of each side is 32/3 cm. If we draw one of the altitudes of the triangle, then a right triangle is formed where the side of a triangle is the hypotenuse, and the altitude is opposite to a 60 degrees angle. So we have, sin 60⁰ = altitude/(32/3 cm) (multiply by 32/3 cm to both sides) (32/3 cm)sin 60⁰ = altitude 9.2 cm = altitude
How would you construct an isosceles triangle if only given the altitude to the base and a base angle?
Start with the altitude (height) and draw that. Draw the actual length of the altitude on your paper, or draw it to scale. Naturally you'll draw it down the middle of your paper parallel to the sides (perpendicular to the bottom) of your paper. Now that you have your altitude, draw a line perpendicular to it across the bottom. Your base will be on that, but we don't know how big it is yet. Let's work with your base angle, but indirectly. You have a vertical line perpendicular to another line. There are two right angles formed, one on each side of the vertical line. If you could draw in one side of your isosceles triangle, you'd have a right triangle that represents half your isosceles triangle. The altitude divides your isosceles triangle exactly in half down the middle. This right triangle will, like all triangles, have interior angles that add up (sum) to 180 degrees. Now we use the base angle. You have the 90 degree angle, and the base angle. That base angle and the "top" angle will add up to 90 degrees, and that's so that these two angles and the 90 angle where the altitude meets the base will add up to 180 degrees. That means the base angle and the top angle will have to add up to 90 degrees. Subtract your base angle from 90 degrees and you'll have your "top" angle. Get you protractor, place it at the top of your altitude, and mark the "top" angle. Now draw a line from the top of the altitude on this angle you set, and continue it to the base. That's one side of your triangle. Repeat this on the other side and your isosceles triangle will appear.
